摘　　要：为研究轮胎花纹深度变化对车辆性能的影响,将不同花纹深度的轮胎作为研究对象,在试验场的干燥路面、湿路面及低附着路面上开展车辆性能试验。结果表明:干燥路面上车辆制动距离随着轮胎花纹深度的减小而减小,湿路面上的趋势与干燥路面相反,低附着路面上花纹深度的变化对制动距离的影响很小;干燥路面上车辆最大侧向加速度与最大横摆角速度随着花纹深度的减小而先增后减,均在4.0 mm处最大;湿路面上车辆的最大横摆角速度呈现与干燥路面一致结果,但最大侧向加速度则无明显趋势。To investigate the impact of variation in tire tread depth on vehicle performance,performance tests are conducted using tires with differing tread depth as our subjects on dry,wet,and low-adhesion road surface at the proving ground.The results indicate that the braking distance decreases as tread depth diminishes on dry surface while the trend reverses compared to dry surface on wet surface,and tread depth variation has a minor impact on braking distance on low-adhesion surface.The maximum lateral acceleration and yaw rate of the vehicle initially increase and then decrease with reducing tread depth on dry surface,peaking at 4.0 mm.The maximum yaw rate follows a similar pattern to dry surface on wet surface,but there is no clear trend in maximum lateral acceleration.
