摘　　要：为了解受电弓在我国高速试验动车组上的性能,对其机械、结构强度进行预判,构建了试验动车组受电弓弓体、底座的有限元分析模型,分析了600 km/h速度工况下,弓体各部件的机械结构强度参数、底座及焊缝关键部位的应力分布,并对弓体结构强度、底座焊缝结构强度、固定螺栓结构强度进行了校核。分析结果表明:试验动车组受电弓的弓体及安装结构强度均在安全系数范围内,能够满足试验列车高速运行的要求。In order to understand pantograph performance on domestic high-speed test EMUs,pantograph mechanical and structural strength was anticipated.Pantograph body and base finite element analysis model of test EMUs was built,and pantograph body parts mechanical and structural strength parameter and stress distribution of base and welded seam was analyzed at 600 km/h speed,as well as structural strength of pantograph body,base welded seam and fixed bolt was checked.Result of analysis showed that the test EMUs pantograph body and its installation structural strength was in the safety factor range,which met the requirements of high-speed test train.
