Abstract

It is known that today the problem of microvibration in spacecraft structures is relevant and widely researched. On- orbit operation of modern spacecrafts such as geodetic satellites, Earth observation satellites or space telescopes is associated with the use of onboard equipment sensitive to micro- vibration. In most cases, the conditions for the normal functioning of precision spacecraft equipment are provided by the operation of electromechanical devices, which in turn are sources of vibration. This article attempts to highlight the main approaches to the microvibration analysis that are known today. In this regard, the analysis of both native and foreign sources, in which the central problem is the analysis of microvibration, is carried out. This paper takes formulation of the microvibration problem and its role in the creation of modern spacecraft process. It also gives a literature review on methods and approaches to the microvibration analysis of spacecraft. Based on the analysis of publications on a similar topic, here one can find the tasks to solve in the process of the spacecraft microvibration analysis. The advantages, disadvantages and limitations of existing approaches and methods are revealed.
