| 摘 要： | 针对线衔接下耦合结构振动传递难以求解的问题，提出具有普遍意义的等效机械导纳方法。以铺板与圆柱壳线衔接结构模型为研究对象，计算各结构的平均振动响应，并与实验结果进行对比，理论计算与实验测试结果一致性良好。研究表明：提出的等效机械导纳法能够有效地计算板壳耦合结构的振动响应特性，且求解过程简单，适于复杂耦合系统振动分析。

| Abstract: | An effective mobility method is presented in this paper to analyze the vibration characteristics of coupled structures under complex exciting. This method is applied to analyze the vibration of a cylindrical shell with an interior plate. As a result, the average vibration acceleration levels of the plate and the shell are acquired. Finally, comparison is carried out between the analytical results by effective mobility method and the experimental ones, which are coincident with each other. It shows that the method presented here is effective, simple, and suitable for vibration analysis of coupled complex structures. |
