摘要
在普通齿轮齿条式被动悬架的基础上,采用偏心叶片泵设计制作了主动悬架系统,建立了车辆1/4模型,应用最优控制理论设计了主动控制器,基于MATLAB/Simulink建立系统模型进行仿真分析。结果表明,此偏心叶片泵式主动悬架对车辆行驶平顺性和乘坐舒适性的改善具有良好的效果,同时该悬架具有主动悬架的性能,且能量可以自给自足。
An eccentric vane pump active suspension system was designed on the ordinary rack and pinion passive suspension basis. A 1/4 vehicle model was established and an active controller of the vehicle active suspension was designed based on the optimal control theory. A system simulation model based on Matlab/Simulink environment was built and used for simulation. The simulation results demonstrated that the eccentric vane pump active suspension could improve automobile riding comfort performance enormously with the performance of active suspension and energy self-sufficient.
