| Abstract: | According to the structure characteristic of the small-satellite,this paper makes a compara-tive analysis of environment property and test effect respectively in terms of theory and experiment of random vibration environment and acoustic environment.Based on analyzing the data of two tests for the same typical small-satellite,module by module,it is concluded that random vibration test is more suitable for small-satellite than acoustic test.The conclusion would be helpful to design a dynamic environment test... |
