A comparison between the results obtained by the finite element method and by measurements is then carried out,considering the size of tire contour,the curve of load-deflection,the contact patch.

Marc软件对子午胎进行了三维非线性有限元分析,分析中考虑了轮胎的材料特性、结构特点、胎圈部与轮辋的摩擦接触以及轮胎与地面的摩擦接触等,比较了轮胎的外缘尺寸、负荷-下沉量曲线以及轮胎接地印痕大小、接地压力分布等,有限元计算结果与实测结果相当吻合。
