带复杂胎面花纹的子午线轮胎有限元分析

Finite Element Analysis on Radial Tire with Complex Pattern

针对205/55R16半钢子午线轮胎,建立带复杂花纹的轮胎有限元模型并进行分析,同时与花纹轮胎的试验结果和光面轮胎的有限元计算结果进行对比。结果表明,复杂花纹轮胎模型与实际轮胎外轮廓、接地印痕吻合较好,花纹对轮胎结构受力特征有一定的影响,就接地性能而言,复杂花纹的存在使轮胎接地压力分布的不均匀性和接地压力水平有所增大。

In this study,the finite element （FE）model of 205/55R16 steel-belted radial tire with complex pattern was established and analyzed. The simulation results were then compared with the test results of the pattern tire and FE simulation results of smooth tire. The results showed that, the profile and footprint of the tire with complex pattern from FE simulation were in good accordance with the actual tire, and tire pattern had an influence on the mechanical characteristics of tire structure. It was also found that the complex pattern would increase the non-uniformity of contact pressure distribution and the level of contact pressure.
