摘　　要：运用有限元分析软件ANSYS对受电弓在抬升力作用下接触网定位器动应力进行了较为详尽的分析,同时对定位器在移动的抬升力和静力作用下的应力进行了比较,并对接触线的拉出值等因素对定位器的影响作了一些分析。由分析结果知,抬升力对定位器动应力的影响是显著的,特别是抬升力作用于定位器时,应力有一较大峰值;接触线拉出值对定位器的静应力也产生了比较大的影响。This paper analyzed the dynamic stress of localizer under the lifting force by using finite element software ANSYS. At the same time,the stress of localizer under the lifting force and static force were compared,the effect of stagger of contact wire on localizer was analyzed. As the analysis results,the lifting force obviously affects the localizer. Especially,when the lifting force acts on the localizer,there is a peak value of the dynamic stress. In addition,the static stress of the localizer is influenced by the stagger of contact wire.
