摘　　要：文中基于有限元分析软件ABAQUS建立了刚性悬挂接触网实体模型,通过改变温度变化范围及悬挂点卡滞位置,模拟仿真了汇流排在定位线夹处卡滞时温度应力对刚性悬挂的影响,分析了刚性悬挂装置化学锚栓应力及中心锚结点的支座反力,给出了不同温度变化及不同卡滞距离下的刚性悬挂锚段的应力场结果,对刚性悬挂接触网悬挂安装设计、施工、运营维护提供参考。The research described in this paper is based on the finite element analysis software ABAQUS,a solid model of the rigid suspension catenary has been carried out.By changing the temperature or the position of the stuck suspension point,the effect of the temperature stress on the rigid suspension when the overhead conductor rail stucked at the positioning clamp has been simulated and quantified.The stress of the rigid suspension device’s adhesive anchor and the reaction force of the midpoint anchor have been analyzed,and the numerical results under the different temperature and different stagnation distances were presented.It provides reference for the design,construction,operation and maintenance of the rigid suspension catenary used on urban rail transit.
