Spacecraft Multifunctional Micro-vibration Environment Laboratory

The problem of orbital micro-vibration has been troubling the development of high-precision spacecraft. Experimental research on on-orbit micro-vibration during the satellite development stage is a very effective method to solve this problem. In order to carry out the ground micro-vibration test of spacecraft with higher accuracy, this paper introduces a micro-vibration laboratory designed in AIT, which has excellent performance of vibration isolation and sound insulation. The background noise index reaches 30 dBA, and the background vibration index reaches 10⁻⁵ g. At the same time, the laboratory is designed according to the satellite development process, which can be used to conduct all kinds of micro-vibration environmental tests in the satellite development cycle under the same background environment.
