摘　　要：基于有限元分析和性能测试对铝合金汽车轮毂进行轻量化设计.首先,利用ANSYS Workbench对轮毂模型进行结构静力学分析,得到车辆静止满载状态下轮毂的应力和变形分布规律.其次,通过对轮毂前6阶模态的分析,得到轮毂各阶固有频率和变形量,并探明轮毂在发动机和路面激励下的共振规律.然后,在轮毂弯曲疲劳、径向疲劳和冲击仿真的基础上,对轮毂轮辐进行拓扑优化以获得轻量化轮毂模型.最后,对轻量化轮毂进行性能试验,并将轻量化轮毂与原始轮毂的试验结果进行对比,分析优化前后的轮毂各项性能的变化,确保轻量化后的轮毂模型符合强度要求.Based on the finite element analysis and performance testing,the lightweight design of aluminum alloy wheel hub is carried out.Firstly,the structural static analysis of the wheel hub model is carried out to obtain the stress and deformation distribution of the wheel hub under the static full load state of the vehicle using ANSYS Workbench.Secondly,through the analysis of the first six‑order modes of the wheel hub,the natural frequency and deformation of each order of the wheel hub are obtained,and the resonance law of the wheel hub excited by the engine and the road is proved.Then,according to the wheel hub’s bending fatigue,radial fatigue and impact simulation tests,the topology optimization of the wheel hub spokes is carried out and a lightweight wheel hub model is obtained.Finally,the lightweight wheel hub is tested again,and the testing results of the lightweight wheel hub and the original wheel hub are compared to obtain the performance changes of the wheel hub before and after optimization,so as to ensure that the lightweight wheel hub model still meets the requirement for strength.
