采用几种新方法和技术对牵引滚动轮胎进行了非线性有限元分析，包括（１）取旋转刚体构形为参考构形，得到消去时间变量的惯性场和控制方程；（２）提出位移梯度约束的概念描述轮胎一地＊面间的切向约束，并用增量约束方法处理滚动接触问题；（３）来用非对称有限元方程组的分块波前解法可以利用中小型微机求解大型非对称有限元方程组。
The nonlinear finite element analysis of traction rolling tire is carried out by several new methods and techniques, including (1) taking the rotating rigid body configuration as a reference configuration, and obtaining the inertial field and the governing equation eliminating the time variable; (2) Proposing the displacement gradient The concept of constraint describes the tangential constraint between the two planes of a tire and the incremental constraint method is used to deal with the rolling contact problem. (3) To solve the problem of large-scale Asymmetric Finite Element Equations.
