子午线轮胎模态分析的有限元方法

轮胎的动态特性是影响车辆整体性能的重要指标之一,文章在充分考虑轮胎材料的各种非线性特性的基础之上,应用ANSYS软件建立了用于子午线轮胎动态特性分析的非线性有限元模型,并针对该模型进行了模态分析,得到了其固有频率及相应的振型。结果证明,该方法具有一定工程实用价值,为轮胎的后续动态分析奠定了基础,并为轮胎特性对整车性能影响的研究提供参考依据。

Application of FEA method to modal analysis of radial tires

Dynamic properties of tires are one of important indexes which affect unitary performance of vehicles. In this paper, a radial tire non-linear finite element analysis(FEA) model is built in the ANSYS environment with the non-linear characteristics of radial tire's materials fully considered,and modal analysis is performed based on this model,then the natural frequency and vibration mode are obtained.The results have a guiding value in practice and are beneficial to the radial tire's other dynamic analyses in succession and the study on contribution of tire properties to the whole vehicle performance.
