摘　　要：文章研究轮胎动力学参数对车辆侧向动力学响应的影响。以Adams/Car为软件平台建立了整车刚柔耦合动力学模型,并验证了所建立模型的准确性。基于该模型以定方向盘转角仿真工况为例,考察了轮胎垂向刚度、侧向刚度及外倾角等参数对横摆角速度、车身侧倾角等侧向动力学响应的影响,为轮胎动力学参数匹配提供一定的参考。This article studies the influence of tire dynamics parameters on the lateral dynamic response of the vehicle.The rigid-flexible coupling dynamic model of the whole vehicle was established with Adams/Car as a software platform,and the accuracy of the established model was verified.Based on the model's simulation of the steering wheel rotation angle,the effects of the tire's vertical stiffness,lateral stiffness,and camber angle on lateral dynamic response,such as yaw rate and body roll angle,were investigated.Matching provides a certain reference.
