A Tailoring Method between Random Vibration and Acoustic Test Based on Area-Mass Ratio for Satellite
2022
Overview
Dynamic environmental tests for a spacecraft are essential in the development stage. In the series of dynamic tests, acoustic test and random vibration test are recognized as two effective spacecraft environmental qualification programs. The current standard and existing technical process for spacecraft indicate that acoustic test and random vibration generally should perform selectively. The vibration test shall be conducted for a small, compact spacecraft, typically with a mass under 450 kilograms, that can be excited more effectively via interface vibration than by an acoustic field. However, it seems inappropriate for complex structure satellites such as lightweight design, large area antenna, large mask camera. In this paper, a tailoring method of random vibration and acoustic test is proposed and verified by simulation analysis and test data.
