城市轨道交通动车组受电弓上框架结构设计方案优化

Optimization of Pantograph Upper Frame Structure Design for Urban Rail Multiple Unit

针对城市轨道交通弓网系统目前存在的问题和障碍,利用简化方法分析了受电弓的整体结构、运动轨迹,以及受电弓的几何运动关系。针对上框架结构,采用有限元分析法对其结构进行了优化计算,经比选提出了较优上框架结构方案。

Targeting at problems and obstacles existing in the pantograph upper frame structure of urban rail transit, a simplified method is used to analyze the overall structure, the trajectory of pantograph and its geometry relations.In view of the upper frame structure, the finite element analysis method is used for the optimizing calculation of the structure.Through a comparison of different schemes, the optimum upper frame structure is selected.
