摘　　要：以新能源汽车行业的蓬勃发展,对驱动电机轴承仿真提出了更高的要求。本文以驱动电机用6009轴承为例,建立保持架柔性化动力学仿真数学模型,应用ADAMS软件中吉尔(Gear)的刚性积分算法以及稀疏矩阵技术,对轴承空载、承受径向载荷、同时承受径向和轴向预紧联合载荷工况条件下滚动体与保持架兜孔之间的碰撞力、保持架运动轨迹等进行仿真分析。通过保持架的受力、运动轨迹分析,可有效预估出保持架结构上的薄弱环节,为轴承设计工作提供理论支持。With the significant development of new energy vehicle industry,more requirements of bearing which is used in electric motor have been put forward,especially in the field of simulation.In this paper,the 6009 deep groove ball bearing is taken as an example to establish the flexible dynamics simulation model,which is based on the ADAMS software and uses the rigidity integral algorithm and sparse matrix technology to analyze the impact force between rolling elements and cage pockets under the conditions of no-load,radial load and combined radial and axial preload.By analyzing the force and motion track of cage,the weakness of cage can be predicted,which can provide theoretical support for bearing design.
