具有细致花纹块的轮胎网格生成及负荷分析

Mesh generation and load analysis considering detailed tread blocks

考虑具有不同深度的细致花纹块,提出一种应用于子午线轮胎三维有限元分析的网格划分程序:首先对轮胎胎体和胎面花纹分别划分网格,然后将两者装配。对具有细致花纹的完全轮胎模型和只有轴向花纹沟的简单半侧轮胎模型进行接地有限元对比分析表明,考虑细致花纹的模型分析结果与测试数据更吻合。

An effective mesh generation procedure applied to 3D finite element analysis of radial tire was proposed, in which the detailed tread blocks with variable depth were fully considered. Tire carcass and tread pattern meshes were constructed independently in the beginning, and then assem- bled. The analysis result of full tire model with detailed tread blocks was compared with the result of simple tire model with circumferential grooves. The results showed that the analysis results of model with detailed pattern were in better agreement with the test data.
