摘　　要：为提高复合材料车轮仿真的准确性,采用高性能长玻纤增强热塑性复合材料作为车轮材料,探索在考虑材料各向异性的情况下联合使用Moldflow,Digimat和Abaqus对车轮强度进行仿真的方法,并针对具体车轮采用该方法按照国家标准进行径向载荷下的强度仿真与分析.研究结果表明:复合材料各向异性特性对车轮应力、应变的分布及最大值均有较大影响;在同一位置是否考虑材料各向异性影响得到的应力值最大相差达314%.该方法可提高长玻纤增强复合材料车轮强度仿真计算结果准确性,可为车轮的进一步轻量化提供参考.To improve the simulation accuracy of composite wheel, a kind of long glass fiber reinforced thermoplastic composite with high performance is used as the wheel material, and the simulation method of wheel strength is explored by combining Moldflow, Digimat and Abaqus and considering the anisotropy of material. The strength of a wheel under radial loading is simulated and analyzed according to the national standard of China. The results indicate that, the anisotropy of material has a great effect on the distribution and the maximum values of the wheel stress and strain; considering the effect of material anisotropy or not, the difference of the values of stress at a same position even reached 314%. The method can improve the strength simulation accuracy of long glass fiber reinforced composite wheel, and also provides reference for the further lightweight design of wheel.
