Abstract
The sinusoidal scanning test is one of the common vibration test methods. The purpose is to test the ability of satellites and their components to withstand low-frequency vibration environment by simulating low-frequency transient environment on the ground. However, the sinusoidal vibration test condition is derived from the equivalent calculation of low-frequency transient environment, and there is no such dynamic environment as “sinusoidal vibration” in actual flight. Therefore, it is necessary to study the equivalence of sinusoidal scanning vibration test method and its difference and influence on spacecraft test. In this paper, the equivalence of sine vibration test conditions is analyzed, and the response of a satellite is calculated by using the original transient excitation, the shock response spectrum (SRS) excitation and its envelopment excitation as input. Then, the reasons for the response results are analyzed, and possible improvements and suggestions are given.
