斜交轮胎静态接地工况的有限元分析

Finite element analysis of bias tire-ground under static contact

建立了斜交轮胎 (9 0 0 2 0 16PR)静态接地三维非线性有限元模型 ,分析了轮胎静接地状态下接触应力分布、接触印痕以及充气压力、下沉量对轮胎接地状态的影响 ,并给出了垂直载荷与下沉量以及最大接触应力与充气压力、下沉量的关系曲线。

A three dimensional non linear finite element model of a bias tire(9 00 20 16PR) with ground contact under static case is developed. The distribution of contact stress and contact area are discussed with different inflation pressure and deflection. The vertical load deflection curve, the maximum contact stress inflation pressure curve and the relations between the maximum contact stress and deflection are given.
