摘　　要：为了给复合材料汽车车轮的设计提供参考依据,根据复合材料力学理论,计算得到碳纤维-环氧(T300/5208)的性能参数,设计复合材料汽车车轮的铺层结构。根据汽车车轮弯曲疲劳实验数据建立该种车轮的有限元模型。通过有限元仿真分析得出最大应力和位移。还用有限元方法对结构相同的铝合金汽车车轮进行分析,并与复合材料车轮进行对比。在工作应力水平近似相等时,复合材料车轮的重量比铝合金车轮的重量小40.74%。在上述条件下,由于复合材料的极限应力比铝合金的大,显然其强度比铝合金的高。In order to provide reference for the design of automobile wheel made of complex material, the performance parameters of Carbon fiber-epoxy （T300/5208） are obtained through calculation and the spreading-layer structure of the wheel are designed according to the complex material mechanics theory. The finite element model of this kind of wheel is established according to the bending fatigue experimental data of automobile wheel. The maximum stress and displacement are gained by finite element simulation analysis. The Aluminum-alloy wheel with the same structure is also analyzed by using this method. The analysis result is compared with complex material wheel. When the working stress levels are approximately equal, the weight of the complex material wheel is 40.74 % less than that of the Aluminum-alloy wheel. In above condition, the strength of the complex material wheel is higher than that of the Aluminum-alloy wheel because the ultimate stress of the complex material is larger.
