摘　　要：为验证某型号地铁空调机箱产品设计是否符合强度要求,建立机箱有限元模型,依据GB/T21563—2008和EN 12663—2000对该空调机箱分别进行冲击性能分析、模态分析、随机振动分析和疲劳性能分析等,获得空调机箱在各种工况下的云图.分析结果表明机箱的设计符合强度要求.To validate that whether the design of air-conditioner cabinet of a metro vehicle meets the strength requirement, a finite element model of the air-conditioner cabinet is built, the impact resistance, mode, random vibration and fatigue performance are analyzed according to GB/T 21563-2008 and EN 12663-2000, and the contours of the cabinet under various working conditions are obtained. The analysis results show that the design of the cabinet meets the strength requirements.
