Computation of the Fatigue Life of Road Wheel with Double-Layer Rubber Flange

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 for rubber, where metal wires are laid in the inner layer and the other layer has no inlaid metal wires. Stress, strain and tempera- ture field of DLRF were calculated with ANSYS finite element analysis(FEA)software, FL of DLRF RW was also computed with fracture mechanics fatigue theory.
