轨道交通市域地铁线路的站台门结构设计方案

Structural Design of Platform Doors for Metro Lines in Urban Rail Transit

论述在高速市域地铁线路最大活塞风载2400 Pa的工况条件下,站台门机械结构的设计方案。针对广州地铁18号线市域地铁车型进行样机结构设计,并通过理论计算和有限元分析验证了样机结构最大变形量满足要求,证明广州地铁18号线站台门整体结构设计方案是可行的。

This paper discusses the design scheme of mechanical structure of platform door under the working condition of maximum piston wind load of 2400pa for high-speed metro line.The prototype structure of Guangzhou metro line 18 is designed,and the maximum deformation of the prototype structure meets the requirements through theoretical calculation and finite element analysis,which proves that the overall structure design scheme of platform door of Guangzhou metro line 18 is feasible.
