设计一种典型标准试验件，对该标准件在单轴与三轴随机振动环境下的响应进行理论仿真，并在三轴振动试验系统上开展试验研究。基于试验响应数据，对试件三轴与单轴顺序加载所造成的相对疲劳损伤进行对比分析，为航天产品振动试验方式的选取提供参考。

A typical simple structure is designed in this paper. The uniaxial and triaxial vibration examinations of the typical structure are done on triaxial vibration examination system, and the fatigue damages of the structure under uniaxial and triaxial excitation are compared. This research gives a train of thoughts to choose more suitable vibration examination fashion.
