摘要
In order to increase the fatigue life (FL) of road wheels (RW), a kind of double layer rubber flange (DLRF) is put forward. It consists of two layers of rubber, where metal wires are laid in the inner layer and the outer layer has no inlaid metal wires. Stress, strain and temperature field of DLRF were calculated with ANSYS finite element analysis (FEA) software, FL of DLRF RW was also computed with fracture mechanics fatigue theory. The results of computation indicate that the heat generated in RW's rubber flange (RF) can be reduced by the use of DLRF, and the FL of RW can be increased without affecting the mechanical intensity of RW.
为提高负重轮的疲劳寿命 ,提出了一种双层橡胶轮缘的方案 .这种轮缘包括两层橡胶 ,内层橡胶加入了金属丝 ,外层橡胶不加金属丝 .用ANSYS软件对这种双层橡胶轮缘的应力应变和温度场进行了有限元分析 ,再用断裂力学理论估算了负重轮的疲劳寿命 .估算结果表明 ,负重轮采用双层橡胶轮缘结构可以减小发热 。
