摘要: 用多体动力学仿真软件ADAMS分别构建多自由度的整车多体动力学模型、道路模型和车-路耦合模型.在这3个核心模型的基础上扩充得到了事故多发路段动力学仿真识别系统.用仿真系统模拟了弯道上不同车速的行车过程.结果显示,仿真结果与汽车系统动力学相关理论吻合.Abstract: A whole vehicle model of multi-body dynamics,a road model,and a tire-road surface coupling model were built using the multi-body dynamics analysis software ADAMS.A simulation system for identifying road accident black-spot was obtained based on the three models.Situations of running on a sharp curve at different speeds were simulated.Simulation results agree reasonably with dynamics of automobiles.
