  • Real-time implementation of Kalman filter for unsteady flow
           measurement in a pipe
    • Authors: Süleyman KaÄŸan Ayaz, à nder AltuntaÅŸ
      Pages: 3 - 15
      Abstract: A Kalman filter which estimates unsteady laminar flow in a pipe is implemented on a real-time computing system. The plant model is the optimised finite element model of pipeline dynamics considering unsteady laminar friction. A steady-state Kalman filter is built based on the model of pipeline dynamics. Pressure signals at both ends of a target section of a pipe are input to the model of pipeline dynamics, and as an output of the model an estimated pressure signal at a mid-point of the pipe is obtained. Difference between measured and estimated pressure signals at the mid-point is fed back to the model of pipeline dynamics to modify state variables of the model. According to the Kalman filter principle, the state variables of the model are adjusted so that they converge to real values. It is demonstrated that real-time implementation of the Kalman filter is possible with the sampling time of 0.1 ms.

  • The influence of rolling bearing clearances on diagnostic signatures based
           on a numerical simulation and experimental evaluation
    • Authors: Ibrahim Rehab, Xiange Tian, Fengshou Gu, Andrew D. Ball
      Pages: 16 - 46
      Abstract: This paper presents investigations into the influences of bearing clearances on the diagnostic features of monitoring rolling-bearings. A nonlinear dynamic model of a deep groove ball bearing with five degrees of freedom is developed for numerical analysis under increased radial clearances which are due to not only the scenarios of bearing grades but also gradual wear with bearing service lifetime. The model incorporates local defects and clearance increments in order to gain the insight into the bearing dynamics under different fault cases along with clearance changes. Numerical results show that the vibrations at fault characteristic frequencies exhibit clear inconsistency with common understandings for different cases of increased clearances. This study highlights that it has to take into account the clearance effect, especially for the inner race fault, in order to avoid the under-estimate of fault sizes which may be indicated by the feature amplitude reduction.

  • An electro-hydrostatic actuator for hybrid active-passive
           vibration isolation
    • Authors: Jean-Paul Henderson, Andrew Plummer, Nigel Johnston
      Pages: 47 - 71
      Abstract: A novel electro-hydrostatic actuator (EHA) for active vibration isolation has been designed, modelled and tested. The EHA consists of a brushless DC motor running in oil and integrated with a bidirectional gear pump, driving a hydraulic cylinder. The actuator is designed to be integrated into a flexible strut connecting a helicopter rotor hub and fuselage, to provide isolation at the dominant rotor vibration frequency of around 20 Hz. The resonant frequency of the EHA is tuned to provide some passive vibration isolation. Active control increases the isolation performance by compensating for damping losses, and provides isolation over a broader range of frequencies. Tests on a prototype demonstrated a four-fold reduction of the root-mean-square transmitted force and a near elimination at the fundamental frequency. The advantages of the resonant EHA are a wider range of operating frequencies than a purely passive system, and lower power consumption than a purely active system.

  • A pin-moment model of flexoelectric actuators
    • Authors: Zhiguo Wang, Zhengqiu Xie, Wenbin Huang
      Pages: 72 - 90
      Abstract: Owning to the unique property of generating pure bending deformation, flexoelectric curvature actuators hold promise for various future applications, especially in the micro and nano scales. This paper proposes three models to predict the deformation of one-dimensional isotropic beams under the excitation of flexoelectric curvature actuators, including the pin-moment model, the pin-force-moment model and Euler-Bernoulli model. The pin-moment model represents the simplest model by only considering the moments interaction between the actuators and the beam at both ends, while the pin-force-moment model incorporate both the force and moment interactions. Comparison between the results of these two models with the Euler-Bernoulli model results indicates that the pin-moment model overestimates the curvature of the beam under a small thickness ratio of the beam and actuator, whereas a good agreement is reached between the pin-force-moment model results with that obtained by the Euler-Bernoulli-model. The accuracy of the pin-force-moment model and the Euler-Bernoulli model was further verified by a finite-element analysis. Therefore the pin-force-moment model could provide a simple and accurate method to characterise the performance of flexoelectric curvature actuators, enlightening the implementation of them for numerous future applications.

  • Independent metering systems
    • Authors: Zhiguo Wang, Zhengqiu Xie, Wenbin Huang
      Pages: 91 - 106
      Abstract: Measures of individualisation and integration offer a great potential for further development and optimisation in hydraulic drive technology. Advantages are seen especially for energy efficiency and functionality. To exploit these benefits the independent metering technology appears to be very attractive which motivates the extensive research on this topic during the last decade. This article starts with a brief overview on common hardware arrangements and general control approaches. Furthermore an approach to the safety evaluation of novel independent metering systems is given. Afterwards different application examples are presented, such as a cardboard packaging press in the area of stationary machines and in the fields of mobile machines a working implement of an excavator and an active steering system for tractors. The article ends with a brief summary of the valve requirements for independent metering.

      Abstract: Future worksites will be occupied by different level of automation work machines. How these machines are working individually and how a fleet of these machines cooperates will be in focus of research and development work in the future. In this paper the studied off-road vehicle is a wheel loader. It can be controlled manually, remotely or autonomously. The control strategy of autonomous wheel loader is consisting of, e.g., static and dynamic mapping, path planning, obstacle observation and avoidance. In the autonomous machines and also in machines where operator assistance system is active the situational awareness is the key research field. Power management in hydraulic work machines are still active fields of research. Multiple architectures and configurations have been suggested concerning this area. In addition, implemented solutions that consider an entire machine are rarely presented. This paper introduces the research work of the control systems which are minimising the fuel consumption.

  • Academic fluid power research in the USA
    • Authors: Zhiguo Wang, Zhengqiu Xie, Wenbin Huang
      Pages: 126 - 152
      Abstract: With the formation of the Center for Compact and Efficient Fluid Power (CCEFP) in 2006, there has been a resurgence of academic fluid power research in the USA. The centre's vision is to make fluid power the technology of choice for power generation, transmission, storage, and motion control. To address fluid power's key technical barriers, the CCEFP research strategy supports and coordinates pre-competitive research in three thrust areas: efficiency, compactness and effectiveness, where effectiveness means making fluid power safer, easier to use, leak free and quiet. This paper reviews some of the most important results from the first decade of CCEFP research.
      Keywords: fluid power; hydraulics; efficiency; compactness; rheology; tribology; seals; Stirling engine; free piston engine; hydraulic pumps; hydraulic motors; valves; digital hydraulics; energy harvester; acoustic silencer; accumulator; displacement control;
