摘要: 忽略胎面花纹形状,利用Rebar单元模型模拟帘线-橡胶复合材料,建立175/65R14型子午线轮胎的三维有限元模型.考虑轮胎橡胶材料非线性、几何非线性、接触非线性等因素,运用非线性有限元分析软件ABAQUS,全面分析了接地轮胎在径向载荷、侧向载荷、纵向载荷、扭转力矩等作用下的变形情况,揭示了轮胎的五刚仿真特性.结果发现,径向、侧向、纵向和包覆刚度特性的仿真结果与试验结果基本一致,扭转刚度特性的趋势与试验结果趋势基本一致,但小于试验结果;总体而言,该仿真方法是有效的.

Abstract:

Proposed in this paper is a three-dimension(3D) finite element model of 175/65R14 tire,in which the tread pattern is ignored and the Rebar element model is used to simulate the composite cord-rubber materials.Then,by taking into consideration the nonlinearities in the aspects of rubber,geometry and contact,the deformations of the tire under radial load,lateral load,longitudinal load and torsion torque are respectively analyzed with the finite element software ABAQUS,and the characteristics of five kinds of stiffness of the tire are simulated.The results indicate that the simulated characteristics of radial,lateral,longitudinal and coating stiffness accord well with the experimental ones,and that the simulated characteristic of torsional stiffness and the experimental one are of the similar tendency though the former is less than the latter.It is thus concluded that the proposed simulation model is effective.
