摘要
针对空间有效载荷特点,采用统计能量法(SEA)进行动力学响应研究。运用该方法建立某有效载荷的SEA计算模型,仿真分析结构整体及关键单元的力学响应,并与实测值进行比对。结果表明,该方法可较好地应用于空间有效载荷力学响应分析,计算精度满足工程要求。
Base on the characteristics of space payload, the dynamics response of the space payload is predicted by the statistical energy analysis （SEA） method. By establishing the SEA model and analyzing the dynamics response of structure and some key components, the simulation results are obtained and compared with test results. It is shown that the SEA method is suitable for analyzing dynarnics response of space payload, and the computational accuracy can meet the engineering requirements.
