中文摘要：
首先分析轮胎的接地特性进行研究,得到了轮胎的接地印迹公式,并通过试验验证了公式的正确性,在此基础上,采用能量法确定胎面单元的侧向刚度计算公式,最后通过数值仿真分析了胎压和垂向载荷对轮胎胎面侧向刚度的影响.
英文摘要：
the characteristics of ground tire was analyzed.The calculation formulas of contact patch of tire were given,which was proved to be correct by experiments.The lateral stiffness of tread was obtained using energy method.Finally,the effects on lateral stiffness of tire pressure and vertical load were analyzed through numerical simulation.
