摘要 分析和建立了人体-座椅的五自由度运动的物理模型以及磁流变阻尼器的修正Bouc-Wen模型,进而提出了车辆磁流变座椅的功率键合图模型,在20-Sim中给出了键合图模型的具体实现。基于此键图模型设计了比例-积分-微分(PID)控制算法。仿真结果表明:该键图模型能够较准确描述整个系统的动态特性,对人体座椅的半主动控制研究具有参考作用。 A five degree-of-freedom(DOF) physical model for human body-seat and a modified Bouc-Wen model of magnetorheological damper are established and discussed.Based on these two models,a power bond-graph model is further presented for the vehicle magnetorheological seats.The bond-graph model is completed with the 20-Sim software.A proportion-integrationdifferentiation(PID) control algorithm is designed based on this bond graph model.Simulation shows that this model can accurately describe the dynamic characteristics of the whole system and provides a valued reference for the semi-active control of human body-seat.
