基于钢结构有限元软件的地铁隔断门门扇结构分析

地下铁道防护密隔断装装置应用于地下铁道，它能在战时把地下铁道空间隔断，并形成大型人防工程，具有明显的战备效益和经济效益，门扇是该装置中最重要的部件之一，应用钢结构有限元软件SAP91建立了地铁防护密闭隔断门门扇的结构模型，并对其进行有限元分析，通过门扇的应力分布及各点位移的结果确定门扇的结构，解决了该装置中直接受力件的结构和强度问题。

Door''s Structure and Its Finite Element Analysis about Protective Closure Obstruction Valve for Subway Civil Defense Engineering based on SAP91

This is the appliance of the patent product to the subway project,which provides the effective sealed property in wartime and establish colossal civil defense engineering at the same time.In this issue,wings are one of the most components.We established the door's model of the protective closure obstruction valve for subway civil defense engineering with SAP91.Analyzing the model we can get it's stress distribution and displacement of each point by finite element method.According to the results,we have determined whether the wings satisfies the given conditions.As well as the use of the SAP91 kit,we successfully settled the structure and the intensity required.
