摘　　要：基于ADAMS建立大轴重铁路货车轴承动力学模型,分析保持架的动力学特性,研究轴承转速、载荷对大轴重铁路货车轴承保持架动力学特性的影响。结果表明:轴承两列保持架运动及接触载荷相差不大;随转速增大,轴承保持架运动及接触载荷幅值明显增大;径向载荷对保持架运动及接触载荷无明显影响。A dynamics model of heavy axle load railway freight bearings is established based on ADAMS.The dynamic characteristics of cages are analyzed,and the influence of rotational speed and load of the bearings on dynamic characteristics of cages is analyzed for heavy axle load railway freight bearings.The results show that the movement and contact load of double row cages are not much different.The movement and contact load amplitude of the cages are increased significantly with increase of rotational speed.The increased radial load has no significant effect on the movement and contact load of the cages.
