箱型船模底部板架流固耦合振动试验研究

Experiment of Fluid-structure Interaction Vibration of Bottom Panel of Box-shaped Ship Model

对钢质箱型船模底板及板架进行了干模态和湿模态试验（包括单面附连水的模态和舱内有液体时的模态），通过试验结果和计算结果的比较，得出了对工程计算中如何处理舱内水问题的相关结论。

The vibration tests both in 'dry mode'and 'wet mode'were carried out for a box-shaped ship model.The model tests in wet mode include the model test in water and the test in water with the liquid in tank as well.The experiment results are compared with calculation,and some conclusions about how to deal with the liquid in the tank in engineering calculation are drawn.
