| 摘 要： | 为提高货车、工程车辆等座椅的减振性能,采用磁流变阻尼器代替座椅悬架中的被动阻尼器,构建半主动车辆座椅悬架系统。针对此系统,利用Adams建立了车-椅-人七自由度的三维多刚体动力学模型,使用Matlab设计了基于专家PID的控制器,并对整个系统进行Adams和Matlab的联合仿真。仿真结果表明专家PID控制策略能使系统较好地抑制垂直振动加速度,提高乘坐的舒适性。

| Abstract: | In order to improve the anti-vibration performance of seat in trucks and engineering vehicles,a semi-active seat suspension system was constructed by applying magneto-rheological(MR) damper to replace the passive damper in traditional seat suspension.According to this system,the three-dimensional multi-body dynamics model of vehicle-seat-human with seven degrees of freedom(DOF) was established using ADAMS and the expert PID controller was designed with MATLAB.The co-simulation of this entire system was carr... |
