装有动力吸振器的汽车悬架性能分析

Study on suspensions with dynamic absorbers

针对普通被动悬架提高平顺性与提高轮胎接地性之间存在的矛盾,引入装有动力吸振器的悬架给出了动力吸振器参数选择的方法,分析了装有动力吸振器汽车悬架的幅频特性和时域性能,并与不装动力吸振器的普通被动悬架进行对比.结果表明装有动力吸振器的汽车可以较好地改善在高频段车身的剧烈振动和轮胎的接地性.

In order to solve the contradict between the road holding and comfort of the vehicle, a suspension with dynamic absorber was proposed. The method of choosing dynamic absorber parameters was (provi-)(ded.) The magnitude-frequency and time-based characteristics of the suspension with dynamic absorbers were analyzed and compared with the suspension without dynamic absorbers. All results show that the suspension with dynamic absorbers can improve vehicle riding comfort and tyre road holding.
