應用ADAMS軟體設計車輛主動式懸吊系統及其實作研究

摘要


本論文主要是以天鉤式(sky-hook)阻尼器為參考模式,利用電液(electro-hydraulic)致動器,追蹤虛擬天鉤式阻尼器之阻尼力,以達到汽車主動式懸吊系統之控制目的。另外,本論文進一步以MATLAB/Simulink軟體來建構控制系統方塊圖並利用ADAMS/VIEW軟體進行動態模擬,由模擬結果可以發現,本文所提出之主動式懸吊系統對於車體振動量和加速度均有明顯的抑制效果。最後利用本文所建構的1/4T主動式懸吊系統實驗裝置,驗證了主動式懸吊不論是在追蹤性能的提昇或是汽車乘坐舒適性的改善均具有顯著的效果。

In this paper, a vehicle active suspension system using a sky-hook damper as the control reference model is proposed. An electro-hydraulic cylinder is utilized to track the desired virtual skyhook damper force. In addition, two commercial software, the MATLAB/Simulink and the ADAMS/VIEW, are used to implement the controller and to simulate the dynamics of the suspension system, respectively. An interface connecting these two software is also developed. Finally, a quarter vehicle active suspension test rig is constructed. The experimental results show that the active suspension system exhibits superior performance of force tracking and significant improvement of the ride quality.
