复杂胎面花纹轮胎有限元三维建模方法

Finite Element 3D Modeling Method of Tire with Complex Tread Pattern

提出一种新的复杂胎面花纹轮胎有限元三维建模方法。将轮胎分为两个独立部分(花纹部分和除花纹以外的轴对称胎体部分)分别建模,该模型可以在二维模式下计算轮辋装配结果并直接传递给三维模型。通过对比胎体帘线受力分布和接地印痕压力分布,检验了模型的有效性,且计算效率较高。

A new finite element 3D modeling method of tire with complex tread pattern was proposed.The tire was divided into two parts,pattern and axisymmetric carcass,and the models of two parts were established independently.With this method,the rim assembling was simulated in 2D model and the results were transferred to 3D model.The validity of the model was verified by comparing the force distribution of the carcass cord and the pressure distribution of tire tread imprint,and the calculation efficiency was high.
