摘　　要：将两种不同自由度的人椅子系统模型附加在车身-车轮子系统上,对比分析不同自由度的人椅子系统对于整个车-人-椅系统动力学特性的影响。通过系统传递函数分析幅频特性。对比结果发现,三自由度的人椅系统模型比单自由度的模型具有明显的减振作用,三自由人椅子系统模型更接近于人体的实际情况。In this paper two kinds of degrees of freedom of human-seat system model are taken in the body – wheel system, and the comparative analysis of the influence of different degrees of freedom of human-seat system model on the whole vehicle dynamics characteristics is per-formed. The amplitude- frequency characteristics are studied through the system transfer func-tion. Comparison analysis results shows that the effect of reducing vibration of three degree of freedom system model is obviously better than that of single degree of freedom model. The three freedom human-seat system model is closer to the actual situation of the human body.
