摘　　要：论文针对某型纯电动客车动力总成悬置支架动刚度不足的问题,采用模态贡献量法找出关键模态,以加权柔度和加权模态最小化为多目标,对悬置支架进行拓扑和形貌联合优化。结果显示,悬置支架动刚度提升的同时,实现了轻量化效果。In view of the problem of insufficient dynamic stiffness of the powertrain suspension bracket nianof a certain type of pure electric bus,the modal contribution method is used to find out the key mode.The topology and topography of the mount bracket are jointly optimized for multiple targets with weighted flexibility and weighted mode minimization.The results show that the dynamic stiffness of the mount bracket is increased while achieving a lightweight effect.
