摘　　要：动力学环境试验技术已得到了广泛的应用,但是动力学环境预示技术还没有得到很好的重视和发展。文章在简要概述了统计能量法(SEA)的基础上,以某卫星为例,划分为26个子系统和97个连接,对整星的宽带声振力学环境的响应进行了估计。经过与试验结果的对比,验证了上述方法的可行性。In contract with the experimental technology of dynamics environment simulation, the prediction technology has not been paid due attention. Based on the Statistical Energy Analysis (SEA), the response of a spacecraft is estimated under a wide-band acoustic vibration environment in this paper, which is divided into 26 subsystem and 97 connections. The results show that the predictions agree with the experimental results well.
