借助多刚体系统动力学的拉格朗日方法对车辆悬架进行研究分析,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车辆悬架系统性能良好。
Based on the multi-body system dynamics Lagrange method, the vehicle suspension is studied and analyzed. The active suspension system model based on the multi-body system dynamics is established, and the theoretical analysis and computer simulation are carried out by nine-point control strategy. The simulation results show that the vehicle suspension system with multi-body dynamics combined with the nine-point control strategy performs well.
