  • ADAMS model validation for an all-terrain vehicle using test track data

    • Authors: Husain Kanchwala, Anindya Chatterjee
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      MD ADAMS® is widely used for vehicle suspension modeling. In this article, we present modeling, simulation, and test track evaluation of an all-terrain recreational vehicle. Our intention is to study the degree to which simplified ADAMS modeling actually matches human-driven vehicle response. For suspension model validation, a vehicle is generally tested on a four-poster test rig and base excitation is applied at four ground-wheel contacts. However, actual driving experience does not match idealized testing conditions. In this work the vehicle is manually driven on a variety of tracks at different speeds, and the vertical accelerations at four axle locations and four body points are measured. The same are then compared in detail against predictions from ADAMS simulation with vertical base excitation. The contribution of this article is in identifying those aspects of the simulation results that match experiments well and identifying possible sources for the observed mismatch, especially under more severe test conditions.

  • Numerical analysis of aerodynamic noise from pantograph in high-speed
           trains using lattice Boltzmann method

    • Authors: Hee-Min Noh
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      A pantograph in contact with a catenary for power supply is one of the major aerodynamic noise sources in high-speed trains. To reduce pantograph noise, it is essential to understand the noise generation mechanism of the pantograph. However, it is difficult to determine this mechanism through measurement. Therefore, in this study, the aerodynamic and acoustic performances of a pantograph in a high-speed train were investigated through numerical analysis using the lattice Boltzmann method. First, a real-scaled pantograph was modeled through computer-aided design. Then, the surface and volume meshes of the pantograph model were generated for simulation analysis. Numerical simulation was conducted at a speed of 300 km/h based on the lattice Boltzmann method. Based on the time derivative analysis of flow pressures, it was concluded that the panhead, joint, and base were the dominant noise sources in the pantograph. In particular, various vortexes were generated from the metalized carbon strip of the panhead. The peaks of the sound pressure level propagated from the panhead were 242, 430, and 640 Hz. The noise generation mechanism was analyzed through numerical simulation using noise characteristics.

  • On the design of a human–robot interaction strategy for commercial
           vehicle driving based on human cognitive parameters

    • Authors: Juan Pablo Vasconez, Diego Carvajal, Fernando Auat Cheein
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      A proper design of human–robot interaction strategies based on human cognitive factors can help to compensate human limitations for safety purposes. This work is focused on the development of a human–robot interaction system for commercial vehicle (Renault Twizy) driving, that uses driver cognitive parameters to improve driver’s safety during day and night tasks. To achieve this, eye blink behavior measurements are detected using a convolutional neural network, which is capable of operating under variable illumination conditions using an infrared camera. Percentage of eye closure measure values along with blink frequency are used to infer diver’s sleepiness level. The use of such algorithm is validated with experimental tests for subjects under different sleep-quality conditions. Additional cognitive parameters are also analyzed for the human–robot interaction system such as driver sleep quality, distraction level, stress level, and the effects related to not wearing glasses. Based on such driver cognitive state parameters, a human–robot interaction strategy is proposed to limit the speed of a Renault Twizy vehicle by intervening its acceleration and braking system. The proposed human–robot interaction strategy can increase safety during driving tasks for both users and pedestrians.

  • Recalculation of the basic static load of ball screws

    • Authors: Huaxi Zhou, Changguang Zhou, Yi Ou, Zeng-Tao Chen
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      Based on the correction factor of accuracy applied in ISO standard 3408-4:2006, this article proposed a modified method to calculate the effective ball number and basic static load rating of ball screws. Meanwhile, the basic static load rating of ball screws was obtained through a new measurement method presented in this article. The experimental results, agreeing well with the theoretical values calculated by the modified method, showed that there is a large discrepancy between the basic static load rating calculated by the traditional method and the measured result, which proves that the new modified method is valid. This study provides a more accurate method to obtain the basic static load of ball screws, which is significant for predicting the performance and service life of ball screws.

  • Theoretical and experimental analysis on deflection control of
           photovoltaic-electrostatic cantilever beam

    • Authors: Yujuan Tang, Yusong Chen, Xinjie Wang, Zhong Yang
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      A model of photovoltaic-electrostatic cantilever beam based on lanthanum-modified lead zirconate titanate ceramic is proposed in this article. New equivalent electrical model of lanthanum-modified lead zirconate titanate ceramic connected to a parallel plate composed of two copper foils is obtained by modifying the original lanthanum-modified lead zirconate titanate equivalent electrical model. After that, the mathematical model of photovoltaic-electrostatic cantilever beam is established. Furthermore, the influences of ultraviolet light intensity and copper foil length on the deflection of the photovoltaic-electrostatic cantilever beam are analyzed via the theoretical and experimental methods. The analysis results indicate that the deflection at the free end of cantilever beam increases with the increase in light intensity and length of the copper foil. The photovoltaic-electrostatic flexible cantilever beam can be taken as a micro-actuator with the advantages of remote control and clean drive.

    • Authors: Cong Li, Hongwei Zhao, Linlin Sun, Xiujuan Yu
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      A novel method for characterizing the tensile properties of AISI 1045 steel is proposed by combining the method of in situ nanoindentation test and the theory of mesomechanical analysis. First, the load–depth curves of exact location of ferrite, pearlite and grain boundary on the surface of AISI 1045 steel are obtained by 30 groups of in situ nanoindentation tests. The constitutive equation (stress–strain function) of the real-time metallographic structure is obtained by nanoindentation analysis of the above curves. Then, based on the principle of mesomechanical analysis, the computational representative volume element models are reconstructed according to the three metallographic images of AISI 1045 steel surface collected by the test equipment. Finally, taking the constitutive equation of the real-time metallographic structure as the input condition, the finite element analysis of the above representative volume element models are carried out. The data resulted from finite element analysis are taken as the tensile mechanical properties of AISI 1045 steel. The elastic modulus of AISI 1045 steel calculated is as the same as that by the traditional nanoindentation method. And, the error is less than 6% compared with the tensile test, which is within the range of the elastic modulus of the material. The error between the yield strength calculated and tensile test results is 3.4%. Due to the influence of surface cracks on the plastic deformation ability of AISI 1045 steel during tension, the error between the strain hardening index calculated and tensile test results is 7.4%. The results show that it is a more accurate nondestructive testing method in the point of material damage mechanism. On the premise of using more accurate representative volume element modelling way, this method is suitable for testing more materials.

  • Numerical analysis of stochastic SIR model by Legendre spectral
           collocation method

    • Authors: Sami Ullah Khan, Ishtiaq Ali
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      This article represents Legendre spectral collocation method based on Legendre polynomials to solve a stochastic Susceptible, infected, Recovered (SIR) model. The Legendre polynomials on stochastic SIR model that convert it to a system of equations has been applied and then solved by the Legendre spectral method, which leads to excellent accuracy and convergence by implementing Legendre–Gauss–Lobatto collocation points permitting to generate coarser meshes. The numerical results for both the deterministic and stochastic models are presented. In case of probably small noise, the verge dynamics is analyzed. The large noise will show eradication of disease, which controls disease spreading. Various graphical results demonstrate the effectiveness of the proposed method to SIR model.

  • Application of model updating techniques to turbomachinery rotor
           components

    • Authors: Roberto Alonso, Joseba Albizuri, Javier Esparza
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      Model updating techniques are commonly used to improve simulation accuracy. Experimental data of component testing under laboratory conditions are normally used to improve analytical predictions of that component under operational conditions. In this study, we have applied these techniques to the dynamics of turbomachinery components. Dynamics of turbomachinery rotor components are normally analysed assuming perfect cyclic symmetry of the basis sector (one blade and its corresponding part of the disc) and this sector is mechanically the same in every angular position. However, the manufacturing process introduces small differences among sectors (mistuning) and changes the global dynamic behaviour. There are several analytical approaches in the literature to model these differences with reduced order models of the whole rotor that include the frequency differences among sectors, which can be obtained experimentally in a component test. Several approaches in the literature use experimental results from a test with a particular set-up in order to obtain the inputs for the models. The approach proposed in this article is just to perform a standard modal test that generates the input for model updating and to extract from the updated model the required input for representing the mistuning phenomena in turbomachinery rotor components.

  • Vibration isolation using a bar and an Euler beam as negative stiffness
           for vehicle seat comfort

    • Authors: Akintoye Olumide Oyelade
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      In this article, the behavior and the efficiency of a nonlinear passive vibration isolator based on a bar and an Euler beam are investigated analytically. The proposed isolator is specifically for isolating vehicle seat from unwanted disturbances in the low frequency range, thereby making the seat comfortable for the driver. The static characteristics of the negative stiffness as well as the nonlinear mathematical model are presented, and its dynamic characteristics are investigated using the harmonic balance method. In addition, the effect of the initial geometric imperfection of the Euler beam is included in the study. The study shows that the performance of the negative isolator has a large isolation frequency range than that of the linear isolator. The configuration parameter choice for the seat base will be vital for the suitable application of this isolator.

  • Analysis of factors affecting drilling friction and investigation of the
           friction reduction tool in horizontal wells in Sichuan

    • Authors: Yong Chen, Chuan He, Xu Zhou, Hao Yu
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      Based on field data and the related theories, the effects of drill string length, rotation speed, trajectory, and drilling fluid density on the friction during horizontal well drilling are analyzed in Sichuan. With increasing the length of drill string in the horizontal section, the friction grows. The drill pipe rotates faster and the torque decreases. Large undulation of borehole deviation and the “W” shape of the horizontal section lead to excessive friction. A higher fluid density causes higher torque and drag. Moreover, a friction reduction tool is designed to reduce friction, decrease the wear between the casing and the drill pipe joint, and prevent the differential pressure sticking, which improves the rate of penetration, and the specially designed spiral diversion channels improve the efficiency of borehole cleaning. The field experimental results have shown that the accumulated operational time of the friction reduction tool is more than 130 h and its fatigue life reaches up to 3 × 105 cycles. A plan of improving the tool structure is proposed to reduce the mud balling after the experiment. Finally, the mathematical model of calculating the spacing of the friction reduction tools is established, which provides technical support for investigating the friction in horizontal well drilling.

  • A spacetime collocation Trefftz method for solving the inverse heat
           conduction problem

    • Authors: Cheng-Yu Ku, Chih-Yu Liu, Jing-En Xiao, Wei-Po Huang, Yan Su
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      In this article, a novel spacetime collocation Trefftz method for solving the inverse heat conduction problem is presented. This pioneering work is based on the spacetime collocation Trefftz method; the method operates by collocating the boundary points in the spacetime coordinate system. In the spacetime domain, the initial and boundary conditions are both regarded as boundary conditions on the spacetime domain boundary. We may therefore rewrite an initial value problem (such as a heat conduction problem) as a boundary value problem. Hence, the spacetime collocation Trefftz method is adopted to solve the inverse heat conduction problem by approximating numerical solutions using Trefftz base functions satisfying the governing equation. The validity of the proposed method is established for a number of test problems. We compared the accuracy of the proposed method with that of the Trefftz method based on exponential basis functions. Results demonstrate that the proposed method obtains highly accurate numerical solutions and that the boundary data on the inaccessible boundary can be recovered even if the accessible data are specified at only one-fourth of the overall spacetime boundary.

  • Rarefied flow and heat transfer characteristics of rectangular cavities
           with heated concave surface

    • Authors: Ammar Alkhalidi, Suhil Kiwan, Wael Al-Kouz, Wahib Owhaib, Aiman Alshare
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      This article utilizes the finite volume method to solve the problem incorporating rarefied flow and heat transfer characteristics inside concaved cavities. Cavities are used in many applications, one of which is building insulation to reduce heat loss from walls. In this article, the influence of the aspect ratio (B/H), the tilt angle (θ), Knudsen number (Kn), and Rayleigh number (Ra) on these characteristics were studied. Parameters ranges were [math]. This study shows that the average Nusselt number (Nu) decreases as the B/H and Kn increase. Whereas, Nu increases with increasing Ra. In addition, the Nu increases as θ increases to a given critical angle (60°), and beyond this angle, Nu decreases with increasing Ra. A new correlation of Nu including all parameters investigated in this work is introduced. This study reveals that concaved cavities could be used as thermal insulation bodies.

  • Determination of the conductivity and thickness of conductive layers on
           conductive base materials

    • Authors: John Burkhardt
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      An eddy current technique for the simultaneous determination of the layer thickness and conductivity of a uniform conductive layer on a known conductive base material is presented. Layer thickness and conductivity are determined by fitting apparent conductivity measurements taken on the surface of the part at a discrete set of frequencies to a calibration volume. The calibration volume is constructed from apparent conductivity measurements taken on a set of known layer materials, of various known thicknesses, as a function of frequency. Experimental results that support the technique are presented.

  • Design and fabrication of a microelectromechanical system resonator based
           on two orthogonal silicon beams with integrated mirror for monitoring
           in-plane magnetic field

    • Authors: Jesús Acevedo-Mijangos, Antonio Ramírez-Treviño, Daniel A May-Arrioja, Patrick LiKamWa, Héctor Vázquez-Leal, Agustín L Herrera-May
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      We present a resonant magnetic field sensor based on microelectromechanical systems technology with optical detection. The sensor has single resonator composed of two orthogonal silicon beams (600 µm × 26 µm × 2 µm) with an integrated mirror (50 µm × 34 µm × 0.11 µm) and gold tracks (16 µm × 0.11 µm). The resonator is fabricated using silicon-on-insulator wafer in a simple bulk micromachining process. The sensor has easy performance that allows its oscillation in the first bending vibration mode through the Lorentz force for monitoring in-plane magnetic field. Analytical models are developed to predict first bending resonant frequency, quality factor, and displacements of the resonator. In addition, finite element method models are obtained to estimate the resonator performance. The results of the proposed analytical models agree well with those of the finite element method models. For alternating electrical current of 30 mA, the sensor has a theoretical linear response, a first bending resonant frequency of 43.8 kHz, a sensitivity of 46.1 µm T−1, and a power consumption close to 54 mW. The experimental resonant frequency of the sensor is 53 kHz. The proposed sensor could be used for monitoring in-plane magnetic field without a complex signal conditioning system.

  • Research on the flexible multibody dynamics of lifting mechanism of
           neutron spectrometer sample table

    • Authors: Yang Li, Yun-xin Wu, Hai Gong, Fu-xia Peng
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      First, the lifting mechanism of neutron spectrometer sample table was designed. Then, every single part flexible multibody models and all parts flexible multibody model were built using ANSYS and ADAMS. Finally, the single part flexible multibody models and all parts flexible multibody model were analyzed when lifting mechanism reached the highest position and sliding table was moving along the X- or Y-axis with 1 ton load. The results indicate that the average deformation along Z direction is maximum among all directions of sliding table center, which is 30.1 μm. Outer cylinder takes up the largest proportion of the deformation in X direction, which is 75.8%, middle cylinder takes up the largest proportion of the deformation in Y direction, which is 91.32%, and inner cylinder takes up the largest proportion of the deformation in Z direction, which is 89.36%. Among the eight guide rails of lifting mechanism, four guide rails between the inner and middle cylinders are under uniform load, and the other four guide rails between middle and outer cylinder are under non-uniform load. The findings of the research could guide the optimal design of the neutron spectrometer sample table.

  • Sustainable eco-design for fixture index mechanism in crankshaft speed
           sensor assembly line

    • Authors: Chelliah Subharaj, Uthirapathi Natarajan, Xevier Hyacinth Suganthi
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      The purpose of this article is to examine the relationship of sustainable manufacturing process and sustainability performance, which considers the environmental, economic, and social aspects. Sustainable manufacturing considering ecological system and corrosion properties has attracted interest in gaining deep insights into the application of daily business operations. Currently, there is an internal pressure in the firms to reduce the costs of production, increase the product quantity with quality, minimize the defects and reliability as well as facilitate faster and flexible delivery. In addition, these firms attempt to seek to satisfy end users and improve operational efficiency. Market pressure, society’s demand for environmental-friendly process, and regulatory compliance are mostly discussed as additional pressure to the green operations initiative in the automotive firms. In this article, an existing model was designed using the computer-aided design software and the results were analyzed to fill research gaps in the effects of the eco-system on environmental and operational performance. This study provides new research opportunities for developing models in building simulation-based design of eco-efficient systems. Finally, the article suggests that the operations should apply parsimony principles of ecosystem measurements to foresee the imminent organizational outcome to enlighten industry counterparts with guidance to enhance further robust statistical modeling and construct development.

  • The examination of the effect of variable cutting speeds on the surface
           and edge qualities of milled granite materials

    • Authors: István Gábor Gyurika, Tibor Szalay
      Abstract: Advances in Mechanical Engineering, Volume 11, Issue 7, July 2019.
      Automated stone manufacturing has undergone considerable development in recent years. Thanks to international research dealing with the cutting, sawing and grinding of different natural stones, processing time shortens and tool-life lengthens. However, the process of stone milling has not been extensively examined yet, primarily because of the novelty of this technology. The aim of the research described in this article is to examine how variable cutting speed affects the quality of workpiece edges while milling granite materials. For the research, sample surfaces were formed on five granite slabs with different average grain sizes using five cutting speed values. Afterwards, changes in the average surface roughness and average edge chipping rate were examined. From the research results, it can be concluded that, due to an increase in cutting speed, the average edge chipping rate will decrease until reaching a borderline speed. In the case of a higher cutting speed, the referent tendency cannot be ascertained. A statistical analysis conducted in the scope of this research showed that if a variable cutting speed is applied, then changes in the quality of the sample surface edge can be inferred from the development trends of average surface roughness.
