摘　　要：基于数据驱动和拓扑优化方法,文章提出一种复杂机械系统振动抑制方法。首先,将机械系统连接结构等效为弹性连接单元,并建立机械系统动力学等效模型;其次,运用数据驱动优化方法对连接参数进行优化设计;最后,以参数优化后系统辅助部件的模态为约束条件,对机械系统连接件进行拓扑优化设计。文章以车辆动力总成系统为对象,对辅助部件连接结构进行优化设计,验证了振动设计方法的可行性。Based on data-driven and topology optimization methods,this paper proposes a vibration suppression technique for com⁃plex mechanical systems.First,the mechanical system’s connection structure is equivalently represented as elastic connection ele⁃ments in order to establish a dynamic equivalent model of the mechanical system.Subsequently,the data-driven optimization method is used to optimize the connection parameters and obtain the optimal parameter combination.Finally,with the modes of the optimal auxiliary component as constraints,the topology optimal design is carried out for the connection structure.To verify the fea⁃sibility of this method,the optimal design is carried out for the connection structure of the powertrain system.
