摘　　要：针对防空导弹的特点和工程应用的需求开展声固耦合动力学分析方法研究。以防空导弹典型舱体结构为例,分别建立有限元模型和统计能量分析模型,结合模型修正后的分析参数,提出了全频段声固耦合分析技术的解决方案,计算得到声振系统全频段的结构和声场响应结果,与试验结果对比,验证了方法的有效性。According to the characteristics of air defense missile and the need of engineer application, the dynamic analysis of acoustic structural coupled system was researched. Based on typical struc- ture of air defense missile, the FEM model and the SEA model were established. With the modified pa- rameter, the solving scheme for acoustic structural coupling analysis in all frequency range was put for- ward, and its structure and response of acoustic field were calculated. Compared with test result, this method proves valid
