摘要
本文运用流体力学、结构动力学及变分原理推导了结构-流体耦合系统的动力学方程,并对水下结构物在运行时的自振特性及动力响应给出了数值计算分析。
Based on the principles of fluid mechanics, the dynamics of structure and the variational principle, dynamic equations for the interaction between the structure and the fluid-the coupled system of structure-fluid, have been deduced. Thus, it provides the feasibility to carry out numerical analyses of the dynamic characteristic and response of a moving structure in the water.
