［摘要］新型地鐵軌道密閉裝置應(yīng)用于地鐵區(qū)間防護(hù)密閉隔斷門，能把地下鐵道空間隔斷，構(gòu)成人防工程，具有明顯的人防效益和經(jīng)濟(jì)效益。在不影響平時通車的前提下，通過采用內(nèi)置仿形橡膠的軌道密封裝置，快速實(shí)現(xiàn)不同受力狀態(tài)的轉(zhuǎn)換，可解決地鐵軌道密封的問題。采用ANSYS軟件對地鐵軌道密封裝置進(jìn)行了非線性接觸分析，研究了密封裝置的變形、應(yīng)力和接觸狀態(tài)，結(jié)果表明，該種密封裝置具有良好的密封性能，為地鐵人防工程建設(shè)提供了可靠的技術(shù)支持和保障。

Abstract: The new type sealing device of subway rail is applicable to new-style double-leaf protective closure blocking door. It can separate subway space into civil defence fortifications, which has obvious civil air beneficial and economic benefit. On the premise of not effecting the daily driving, by using sealing device with inner rubber, the transformation of different force states is realizing and the protective and closure problems are solved effectively. Using ANSYS finite element software, nonlinear analyses involving contact stress and deformation were performed for sealing device. Results show that this kind of sealing device has a good sealed performance. It provides the reliable technical support and security for civil defense engineering of metro.

Keywords: subway rail; sealing device; finite element analysis
