Abstract： This paper introduces the overall design principle and structure composition， as well as the structure design and installation of the main components of the equipment， of the equipment cabin of the high-speed commuter train. The technology of high-speed commuter train equipment cabin system adopts modular design concept， reasonable structure layout and simple operation. At the same time， the overall strength of the equipment cabin is calculated and verified by the finite element analysis software.

Keywords： high-speed commuter train; equipment cabin; structural design; static strength; fatigue strength

市域動(dòng)車組在軌道上高速運(yùn)行時(shí)，面臨非常復(fù)雜的外部環(huán)境，如列車運(yùn)行和交叉口產(chǎn)生的氣壓波，運(yùn)行中遇到的雨、雪、風(fēng)暴，以及外部物體對列車下方區(qū)域的高速?zèng)_擊。（剩余3770字）
