摘要
用磁流变阻尼器代替传统座椅悬架中的被动阻尼器,构成半主动车辆座椅悬架系统。针对此系统建立"人-车-椅"14自由度力学模型。其中阻尼器采用双曲正切磁滞模型,并选取PID控制器,在Matlab/Simulink环境中建立整个系统模型,输入标准路谱信号进行仿真。仿真结果表明,该控制器能较为有效地改善座椅减振性能,提高乘坐舒适性。
Using magnetorheological damper instead of passive damper,the passive semi-active seat vehicle suspension system is constituted.a human-car-seat 14 degrees mechanics model is established for this system,in which a hyperbolic tangent hysteresis model is used for the magnetorheological damper,a PID algorithm is selected in the controller,and the standard road spectrum is taken as the input of the whole system in the Matlab/Simulink based simulation model.Simulation results show that the controller can effectively improve the seat performance,comfort.
