【摘要】 建立了一种考虑高速船舶在波浪稳态激励作用下的水弹性分析方法。将用于分析刚体运动流体动力的二维半理论加以扩展,求解了弹性体运动产生的广义流体力。应用基于三维有限元的模态分析法计算了一条高速双体船模在波浪中运动和载荷的水弹性响应。理论结果和模型试验结果符合的较好。数值分析表明本文方法能够用于高速船舶水弹性分析。更多还原

【Abstract】 This paper presents a method to solve the springing responses of high speed vessels in regular waves .The 2.5D theory for calculating the hydrodynamics of rigid body motions is extended to solve the wave radiation potential due to elastic deformation of ships .Modal analysis method based on 3D finite element technology is applied to calculate the hydroelastic responses of ship motions and wave loads .The numerical results agree well with the experimental dada .Numerical analysis shows that the present method can be used to predict the hydroelastic property of high speed vessels.更多还原
