| Abstract: | As to the crack problem of polyurethane rubber friction wheel of automobile skateboard conveyor, the finite element analysis on the preload tension and contact friction driving is performed for the interaction between the friction wheel and skateboard, and then the distribution of stress and deformation is obtained. Based on the circumferential stress distribution of friction wheel, according to the fatigue crack propagation formula, the fatigue life of polyurethane rubber of friction wheel is analyzed to verify if the fatigue life meets the design requirement. The analysis process and results can provide reference for the detailed design of the polyurethane rubber friction wheel. |
