| 摘 要： | 为研究流固耦合模型受强迫激励时的响应局部化现象，用假设模态法建立系统振动的数学模型．考虑结构长度非对称，分析模型在低阶固有频率范围内产生的响应局部化现象．结果表明，在非对称参数较小时，结构响应局部化随非对称参数的增大而加强．水的耦合作用对上下板的响应局部化程度影响不同。

| Abstract: | To study the forced response localization phenomenon of asymmetric plate-type structures in still water, the assumption mode method was used to derive the vibration model. The analysis was focused on the asymmetric length of the structure and low order natural frequencies. The results show that the response localization of the model becomes stronger with an increase in asymmetry of structure when the asymmetry is small, the coupling effects of water on the upper and lower plates are different. |
