中文摘要：

为开发符合动态特性的轻质车轮,用ANSYS Workbench软件建立镁合金车轮的模型,对车轮的弯曲和径向疲劳试验进行动态模拟和分析.为使车轮应力分布更合理,提出先确定质量设计结构,再比较应力的优化方法,并用此方法对车轮的轮辐和螺栓孔个数进行优化.结合拉丁超立方抽样和正交设计对车轮的结构参数进行最优化设计.最终设计出的车轮在减重37％的基础上仍满足动态疲劳性能.

英文摘要：

In order to develop a lightweight wheel that can satisfy the dynamic characteristics, the magnesium alloy wheel model was built up, the dynamic bending and rolling fatigue tests were simula- ted and analyzed by ANSYS Workbench. To gain more reasonable stress distribution of wheel, the method that first determined mass and designing structure, then comparing stress was proposed, and it was used to optimize spokes and bolt holes＇ number of wheel. Then the wheel＇ s structure parameter was optimized by combining Latin hypercube sampling and orthogonal design. The optimized wheel reduced 37% of its weight, and can also achieve the dynamic fatizue nerformance_
