行驶面宽度和弧度高对轮胎偏磨损影响的有限元分析

以12.00R22.5全钢载重子午线轮胎为例，利用Hypermesh和Abaqus有限元分析软件研究行驶面宽度和弧度高对其偏磨损的影响，采用接地区域摩擦功偏度值评价轮胎的偏磨损。结果表明：轮胎径向刚度和侧向刚度的有限元分析结果与试验结果具有良好的一致性；轮胎行驶面宽度和弧高的变化使胎面不同区域的摩擦功发生变化；随着行驶面宽度增大，轮胎的偏磨损减少；随着行驶面弧高增大，偏磨损增加。;Taking the 12.00R22.5 truck and bus radial tire as an example，the effect of running surface width and arc height on the uneven wear of the tire was investigated by finite element analysis software Hypermesh and Abaqus，and the uneven wear of the tire was evaluated by the skewness value of friction work in the grounding area. The results showed that，the finite element analysis results of radial stiffness and lateral stiffness of tire had good consistency with the test results. The change of running surface width and arc height changed the frictional work in different areas of tread. With the increase of running surface width，the uneven wear of tire decreased，and with the increase of running surface arc height，the uneven wear of tire increased
