摘要
提供了一种考虑薄膜力影响的海上浮动平板的水弹性频域分析方法。在线性假定下利用格林函数法求解浮动平板所受的波浪作用力和在水中运动的附加水动力系数。根据板的大挠度理论 ,考虑板内的薄膜力 ,建立了波浪中运动平板的水弹性运动方程。在求解了由一阶波浪力引起的板的一阶位移后 ,通过对与该位移有关的薄膜力引起的非线性力的频率分析 。
Considering the influence of the membrane forces, a hydoelastic analysis method of a floating plate in frequency domain is presented. With the Green function method, the hydrodynamic coefficients of the floating plate are calculated under the linear assumptions. According to the theory of a plate with large deflections, the motion responses equations of a floating plate are established considering the influence of the membrane forces. By analyzing the frequency characteristics of the nonlinear forces induced by the membrane forces that have the relationships with the first order vertical displacements induced by the wave exciting forces, the solution method of the nonlinear vertical displacements induced by the membrane forces are proposed.
