| 摘 要： | 基于LS-DYNA非线性有限元分析软件,建立具有复杂胎面花纹的175/65R14子午线轮胎三维有限元模型.通过轮胎径向刚度试验验证所建轮胎有限元模型的有效性,并在此基础上构造轮胎水滑仿真分析模型.使用ALE算法处理轮胎与水流间的流固耦合关系,仿真分析轮胎从静止到水滑现象产生的全过程,获得的轮胎临界水滑速度与经验公式的计算结果具有较好的一致性.3种不同花纹轮胎水滑速度仿真结果在趋势上与预期一致,进一步说明了有限元方法对轮胎水滑特性仿真评价的有效性.

| Abstract: | The detailed model for 175/65R14 radial tire with 3D complex pattern was constructed by LS-DYNA finite element analysis software.The model was validated with experimental data of radial stiffness and numerical model of hydroplaning was obtained based on it.Meanwhile,the fluid-structure coupling was characterized by the algorithm of ALE.Through the numerical analysis,the whole tire hydroplaning phenomenon was simulated and critical hydroplaning speed was obtained,which was quite consistent with the theoretic... |
