飞行振动环境实验室模拟的有效性分析

Validity Analysis for Laboratory Simulation of the Flight Vibration Environment

本文在简要介绍了实验室模拟实际飞行环境的振动试验方法后，采用频响函数理论，以随机振动响应功率谱等效为目标，分析了该方法模拟有效的条件，指出了实际应用中应注意的几个关键环节以及尚需进一步研究的问题。

In this paper, vibration test method of simulating practical flight environment is briefly introduced. According to the theory of frequency response function, validity for the method is analyzed in which equivalence is based on producing a similar power spectrum response between the field and laboratory. Several problems that should be noted in application are presented.
