摘要
导出置于液面上的复合材料迭层板变形时流体作用力的近似表达式 ;由 Ham ilton原理建立了考虑横向剪切变形以及流固耦合效应时迭层板的非线性动力方程 ;采用差分方法求解了迭层板的非线性流固耦合动力响应 ;
The approximate expression of the fluid force between a floating laminated composite plate and liquid surface is obtained in this paper. Nonlinear dynamic equations including the effects of transverse shear deformation and solid fluid interaction are established by Hamilton's principle. The nonlinear dynamic solid fluid interaction response is solved by means of a difference method. The effects of non linearity and fluid depth under different loading forms on dynamic response are discussed.
