汽车悬架多刚体动力学分析及九点控制

汽车机械系统的建模、分析与求解始终是动力学的关键问题，为快速准确地求解分析，文章借助多刚体系统动力学的拉格朗日法对汽车悬架进行分析，建立了基于多刚体系统动力学的主动悬架系统模型，并采用九点控制策略进行了理论分析和计算机仿真。仿真结果表明，以多刚体动力学方法同九点控制策略相结合的汽车悬架系统性能良好。

Vehicle Suspension Multi-body Dynamics Analysis and Nine Point Control

Modeling,analysis and solving of vehicle mechanical system is the key problem of dynamics.In order to solve and analyze quickly and accurately,analysis on vehicle suspension by the Lagrange's method of multi-body dynamics was presented and based on the multi-body system dynamics a model of active suspension system was established.Nine point control strategy was adopted to perform theoretical analysis and computer simulation.The results showed that the vehicle suspension system based on a multi-body dynamic ...
