辐板式全塑轮胎材料选择及结构分析

以辐板式全塑轮胎为对象,以实现注塑成型为目的,选用新型注塑型记忆性高分子材料TR90,提高轮胎的使用性能。采用Abaqus有限元分析软件,对轮胎的轮辐数量进行数值优化,研究轮辐数量对轮胎的力学强度、下沉量及接地面积的影响。结果表明:新材料能够满足轮胎的性能要求;轮辐数量为30条时,轮胎最大应力、下沉量和接地面积在两极限位置差异较小;与同规格充气子午线轮胎相比,30条轮辐全塑轮胎的下沉量和接地面积分别增大6.8%和5.4%,为最优结构设计。

The Materials Selection and Structural Analysis of Plastic Tires with Wheel Spokes

In this paper, the new materials was used for plastic tires with wheel spokes to achieve injection molding and improve the performance of plastic tires. The number of wheel spokes was optimized by numerical simulation by using ABAQUS software, the effect of the number of wheel spokes on mechanical strength, deflection and contact area was studied. It showed that the material could meet the requirements of tire properties. When the number of wheel spokes was thirty, the difference between two positions was relatively low in terms of the maximum stress, the deflection and contact area. The deflection and contact area of thirty spokes tires were 6.8% and 30.7% times higher than those of pneumatic tire, respectively.
