摘要
针对北京中车赛德公司自主研制的一种新型受电弓进行研究分析,利用ANSYS软件对其结构强度和焊缝结构应力进行有限元仿真分析,通过仿真计算及理论分析找出设计缺陷及不足之处,同时根据分析结果对其改进设计提供切实可靠的理论依据。
This essay mainly research the autonomous pantograph which made by Beijing CRRC CED company.ANSYS software is Utilized to analyze the structural strength and stress of the weld structure,through the simulation calculation and theoretical analysis to identify the design flaws and shortcomings.At the same time,the analysis results provide a reliable theoretical basis to improve its design.
