摘　　要：主要介绍了不同垂向刚度的测试方法的区别,同时分析了轮胎侧倾角、滚动速度及加载频率对轮胎垂向刚度的影响。结果表明:随侧倾角的增加,轮胎静态垂向刚度先增加后逐渐减小;随滚动速度增加,轮胎动态垂向刚度先减小后逐渐增加,且在一定速度范围内,轮胎动态垂向刚度小于速度为零时的刚度;随加载频率的增加,轮胎动态垂向刚度逐渐增加。This article mainly introduces the differences in testing methods for different vertical stiffness,and analyzes the effects of tire roll angle,rolling speed,and loading frequency on tire vertical stiffness.The results indicate that as the roll angle increases,the static vertical stiffness of the tire first increases and then gradually decreases;As the rolling speed increases,the dynamic vertical stiffness of the tire first decreases and then gradually increases,and within a certain speed range,the dynamic vertical stiffness of the tire is less than the stiffness at zero speed;As the loading frequency increases,the dynamic vertical stiffness of the tire gradually increases.

关 键 词：轮胎刚度 侧倾角 滚动速度 加载频率
