摘　　要：为紧随新时代铁路运输快捷、重载货运趋势,该文面向针对货运低动力、低磨耗需求的径向转向架技术,主要分析径向转向架特点,梳理、总结径向技术主流类型,并选取货车转向架中代表性副构架式径向转向架进行研究。该文针对副构架式径向机构,解构其结构组成,运用有限元仿真分析方法对副构架静强度、疲劳强度进行研究。仿真结果显示,径向装置整体强度满足要求,局部区域应力需引起关注,可为后续径向转向架设计、制造与研究提供一定参考。In order to follow the trend of fast and heavy-haul freight transportation in the new era,this paper mainly analyzes the characteristics of radial bogies,summarizes the mainstream types of radial technology,aiming at the radial bogie technology with low power and low wear demand.and select the representative sub-frame radial bogie in the freight car bogie to study.In this paper,aiming at the sub-frame radial mechanism,its structural composition is deconstructed,and the finite element simulation analysis method is used to study the static strength and fatigue strength of the sub-frame.The simulation results show that the overall strength of the radial device meets the requirements.Local stress needs attention,which can provide some reference for the design,manufacture and research of subsequent radial bogies.
