摘　　要：为满足某型航天产品振动试验要求,设计了一个航天产品的振动工装。利用Unigraphics NX (UG)软件对设计的振动工装进行建模,利用Hypermesh软件进行有限元分析前处理,利用MSC.Patran/Nastran软件进行有限元分析。分析振动工装的基频、正弦振动时的加速度、应力与应变响应以及随机振动时的应力响应,分析结果表明所设计的振动工装能满足试验要求。In order to meet the vibration test requirements of a aerospace product, a vibration tooling for aerospace product was designed. Unigraphics NX(UG) software was used to model the designed vibration tooling,Hypermesh software was used for pre-processing of finite element analysis, and MSC.patran/nastran software was used for finite element analysis. The basic frequency of vibration tooling, acceleration, stress and strain response during sinusoidal vibration, and stress response during random vibration were analyzed. Through analysis, it can be preliminarily confirmed that the designed vibration tooling can meet the test requirements.
