摘要
分析了当前常用车辆油气悬架减震装置的特点和性能要求,根据油气悬架质量的主要评价指标提出了对油气悬架加载试验系统的功能要求和性能要求。从机械、液压、电气以及控制几个方面进行了加载试验系统的设计。设计中应用ANSYS软件对系统机械结构进行了分析,应用MATLAB的SIMULINK工具对控制器中的三状态控制方法(TVC)、幅相控制方法(APC)以及变刚度自适应力控制方法(SFC)进行仿真设计。试验结果表明,这3种控制方法对于车辆油气悬架加载试验系统在位置控制、加速度控制以及主动力控制中取得了良好的效果,有效地提高了随机波与正弦波复现精度。
ANSYS software was used to analyze the system mechanism and MATLAB/SIMULINK was used to simulate and design the controller using three variable control (TVC),amplitude phase control (APC) and variable-rate self adaptive force control respectively after analysing the feature,performance and main test methods of the vehicle oil gas suspension equipment and presenting functional requirement and performance requirement based on the evaluating indicator of oil gas suspension quality.The test system was designed based on mechanical,hydraumatic, electricity and control.The test results show that using these three control methods in position control,acceleration control and drive force control of vehicle oil gas suspension load test system has well effect and improves the accuracy of random wave recurrence and sine wave recurrence,this test apparatus has a good prospect of application for the same system.
