基于ANSYS子午线轮胎静态特性的有限元分析

Finite element analysis of radial tire static characteristics based on ANSYS

利用ANSYS有限元软件建立了子午线轮胎的有限元模型,计算了在胎压载荷和汽车重力载荷作用下轮胎的变形、应力和接地压痕。计算显示胎侧部分刚性低,变形量最大,轮胎中心区的应力最大,接地压痕随载荷增大而增大,这些符合实际情况,分析对于轮胎的设计和应用具有一定的指导作用。

The finite element model of radial tire is established by ANSYS,and then the deformation,stress and indentation of tire are calculated under tire pressure load and vehicle gravity load. The results show that the deformation of the sidewall is the largest as its small rigidity,and the stress in the center of the tire is the maximum,the ground indentation increases with the increase of the load,which are in line with the actual situation. The analysis has guiding function for the design and application of the tire.
