摘　　要：航天器在轨运行期间,在各种扰源作用下会产生一种加速度幅度小、频率分布广的微振动,将严重澎响高精度航天器有效载荷的指向精度和姿态稳定度。本文针对规范茹推广航天器微振动试验的需扎从标准化的角度研究了航天器在轨微扰动源、航天器自由边界模拟、背景噪声控制等航天器微振动试验餉方法和要求,分析了国内航天器微振动试验方法的发展方向及相关标准需求,提出了航天器微振动试验标准体系。During the on-orbit operation of spacecraft,a kind of micro-vibration with small acceleration amplitude and wide frequency distribution will occur under the action of various disturbing sources,which will seriously affect the directional accuracy and attitude stability of high-precision spacecraft payload.Aiming at the requirement of standardization and popularization of spacecraft micro-vibration test,this paper studies the on-orbit micro-disturbance source,spacecraft free boundary simulation and background noise control from the standardized point of view by summarizing spacecraft micro-vibration environment,test methods and implementation means,analyzes the development direction of spacecraft micro-vibration,test methods and related standard requirements,and puts forward the standard system of spacecraft mi-cro-vibration test.
