- 摘要:
- 利用有限元软件的接触单元和非线性分析技术,建立汽车轮胎与道路接触的有限元分析模型,研究了在一定胎压、车身自重及一定水平加速度的作用下,轮胎与道路接触的应力及其应变分布情况.研究结果表明:轮胎接地部分接触应力最大,轮胎两侧位移呈对称分布,胎侧下端中部变形最为明显; 在轮胎周向,横向变形从轮胎接触部分向胎圈部位逐渐过渡,变形逐渐减小.
- Abstract:
- The finite element analysis model of automobile tire and road contact is established by using the contact element and nonlinear analysis technology of finite element software. To study the stress and strain distribution of the tire in contact with the road under certain acceleration, tire pressure and vertical load. The results show that the contact stress of the grounded part of the tire is the highest. The lateral displacements of the tires are symmetrically distributed, and the deformation is most obvious in the middle of the lower end of the fetal side.In the circumferential direction of the tire, the lateral displacement gradually transfers from the contact part of the tire to the position of the tire rim, and the deformation gradually decreases.
