基于ADAMS/Car某客车操纵稳定性的仿真与分析

摘要

According to the numerical model and kinetic parameters,the entire virtual prototyping model of the bus is established with ADAMS/Car software,and the simulation tests for the whole bus are performed by the method of snakelike test.Meanwhile the virtual evaluation and analysis are also performed for the simulation results,such as the average steering wheel angle,the average yaw velocity,the average vehicle roll angle,the average lateral acceleration and so on.By comparative analysis of the simulation results'datum,the correctness of the virtual prototyping model is verified, which provide the basis for further study of the entire vehicle dynamics.%根据某客车的数模及动力学参数,在ADAMS/Car软件中建立该车的整车虚拟样机模型,根据蛇形试验的方法,对整车虚拟样机模型进行了蛇形试验的仿真分析,并对其仿真结果如平均转向盘转角、平均横摆角速度、平均车身侧倾角、平均侧向加速度等进行了虚拟评价分析.通过仿真结果数据的对比分析,说明了虚拟样机模型仿真试验的正确性,从而也为整车动力学进一步研究奠定了基础.
