- Gear Hobbing Process Parameters Optimization Decision Based on AHP and CBR
Abstract: Gear Hobbing Process Parameters Optimization Decision Based on AHP and CBR
Author Weidong CaoChunping Ya
To retrieve previous process cases efficiently, and improve integrated processing effect, this paper proposes gear hobbing process parameters optimization decision based on analytic hierarchy process (AHP) and case-based reasoning (CBR). Gear hobbing process ontology library was conducted by Ontology. Considering the processing quality, processing time, processing costs, resource consumption and environmental impact, Gear hobbing process parameters decisions target space was established by using gear hobbing process ontology library and CBR. AHP was used to get the optimal decision program. The feasibility and effectiveness of the proposed method is validated by experiment.
- Research of Anti-sway System for ARMG Based on Input-shaping Control
Abstract: Research of Anti-sway System for ARMG Based on Input-shaping Control Method
Author Gang LiuJin-Gui LuoChun XieChristian Sponfeldne
This paper did research on electric-control anti-sway system with input shaping method, which is different from commonly used closed-loop PID and Fuzzy-logical control. Input shaping technique is a feed-forward control technique that involves convolving a desired command with a sequence of impulses known as “input shaper” to damp motion induced oscillations. Based on Matlab/Simulink the input shaper inside an embedded Matlab-function-block was implemented. By comparision, although the IS-controlled system reaches the desired position later, but swings inside the tolerance zone, which makes it more efficient.
