摘　　要：文章从能量守恒定律出发,结合转臂式轴箱定位装置的结构特点,通过分析其受力状况和运动几何关系,在充分合理简化的基础上,推导出通用的转臂式轴箱定位装置的垂向、纵向和横向等效刚度计算公式,并对我国典型动车组的转臂式轴箱等效定位刚度进行了计算。This paper begins from the law of conservation of energy,with the combination of the structure features of the rotary arm type axle box guidance,through the analysis of the force conditions and the moving geometrical relations,on the basis of the fully reasonable simplification,the calculation formula of vertical,longitudinal and lateral equivalent stiffness for the universal rotary arm type axle box guidance is deduced,and the equivalent stiffness of rotary arm type alxe box guidances for typical multiple units in our country are calculated.

关 键 词：转向架 转臂式 轴箱定位 等效刚度
