| 摘 要： | 水动力学与固体力学交叉的流固耦合理论是船舶与海洋工程结构响应分析与直接设计的重要工具.本文应用卷变积方法,按照广义力和广义位移之间的对应关系,将弹性动力学的基本方程卷乘上相应的虚量,然后积分,代数相加,并考虑到体积力和面积力均为伴生力,建立了非保守系统初值问题的两类变量的广义拟余能原理.应用广义拟余能原理研究流固耦合问题,分析了结构的动力响应,给出同时求解力类量和位移类量两类变量的计算方法.

| Abstract: | The fluid-solid coupling theory,an interdisciplinary science between hydrodynamics and solid mechanics,is an important tool for response analysis and direct design of structures in naval architecture and ocean engineering.By applying the corresponding relations between generalized forces and generalized displacements,convolutions were performed between the basic equations of elasto-dynamics in the primary space and corresponding virtual quantities.The results were integrated and then added algebraically.In ... |
