摘　　要：为提高汽车轮毂的刚度、强度、可靠性等,降低汽车轮毂的成本和质量,采用Altair Inspire软件对汽车轮毂进行初始强度分析和拓扑优化。首先,根据汽车轮毂初始的几何形状、载荷条件、约束条件和材料属性建立有限元模型,进行线性静力学分析,获得汽车轮毂的米赛斯应力、最大位移和最小安全系数分布云图。然后,利用Altair Inspire的拓扑优化功能对汽车轮毂进行结构拓扑优化,获取轮毂的轻量化概念实体模型。对比分析优化前后汽车轮毂模型的结构性能指标,结果表明,Altair Inspire的拓扑优化方法可以有效改善轮毂的结构性能指标,最佳方案优化模型实现了28.9%的减重,最大米赛斯应力降低了2 MPa,最大位移降低了1.39μm,最小安全系数提升了0.1。To improve the stiffness,strength,reliability,and reduce the cost and quality of automotive wheels,Altair Inspire software was used for initial strength analysis and topology optimization of automotive wheels.Firstly,based on the initial geometric shape,load conditions,constraint conditions,and material properties of the car wheel hub,a finite element model was established for linear static analysis to obtain the Mises stress,maximum displacement,and minimum safety factor distribution cloud map of the car wheel hub.Then,the topology optimization function of Altair Inspire was used to optimize the structural topology of the car wheel hub in order to obtain a lightweight conceptual entity model of the wheel hub.Finally,compared and analyzed the structural performance indicators of the car wheel hub model before and after optimization.The results showed that the topology optimization method of Altair Inspire could effectively improve the structural performance indicators of the wheel hub,and the optimal scheme optimized the model to achieve a weight reduction of 28.9%,a maximum Mises stress reduction of 2 MPa,a maximum displacement reduction of 1.39μm,and a minimum safety factor improvement of 0.1.
