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。针对此系统建立七自由度"人体-座椅-车辆"动力学模型,并为该系统设计模糊控制器,同时在随机路面激励下对于该系统进行仿真分析。仿真结果表明模糊控制能够使系统较好地抑制垂直振动加速度,提高乘坐的舒适性。
In order to improve the seat anti-vibration effect of truck and engineering vehicle,a semi-active seat suspension system is constructed by using magneto-rheological（MR） damper to replace the passive damper of traditional seat suspension.A human-body-seat with seven-DOF of multi-body dynamics model is established and its corresponding fuzzy controller is designed.The simulation on the system is completed by the random roughness of road surface input model.Simulation results show that fuzzy scheme can effectively attenuate the vertical acceleration and increase the riding comfortableness as well.
