摘要
水下运行的结构与反馈的流体形成相互作用的流固耦合问题，利用莫里森公式计算结构的附连水质量，得到考虑流固耦合影响以后的结构自振特性及动力响应结果．
A fluid structure coupling is raised by the interaction of a submerged moving structure with the fluid around.By use of MORISON formula,added water mass is calculated.The natural frequencies and modal characteristics of structure are obtained after considering the influence of fluid structure coupling and the dynamical response of structure is given also.
