摘要
分析了置于无族不可压理想流体流面上的简支刚塑性圆板受矩形脉冲载荷作用的大挠度动力响应，借助Ｈａｎｋｅｌ变换，将液－固耦合作用转化为在空气中的圆板塑性动力响应问题，进而求解弯短和膜力联合作用的大挠度运动方程，得到了中载及高载下各相运动的完全解，并提供了数值算例．
A Study is presented for the large deflection dynamic response of rigid-plastic circular plait resting on potential fluid under a rectangular pressure pulse load. By virtue of Hankel integral transform technique, this interaction problem is reduced to problem of dynamic plastic response of the plate in vacuum. The closed-form solutions are derived for both middle and high loads by solving the equations of motion with the large deflection in the range where bending moments and membrane forces both are important. In the end, some results are given.
