摘　　要：本文建立了桁架式超大型浮体(VLFS)构型方案,并采用迁移矩阵法进行模态分析;然后,基于三维水弹性理论方法,对该VLFS进行了运动与载荷响应计算,分析了不同海况和浪向角对浮体运动与载荷响应的影响;最后,将水弹性计算结果与基于刚体假设的载荷计算结果进行了对比,以分析弹性效应对浮体波浪载荷的影响。In this paper,the configuration scheme of truss type very large floating structure(VLFS)is established,and the modal analysis is carried out by using the transfer matrix method.Then,based on the threedimensional hydroelastic theory,the motion and load response of VLFS are calculated to analyze the influence of movement and load response in different sea conditions and wave directions on the floating structure.Finally,the hydroelastic calculation results are compared with the load calculation results based on rigid body hypothesis to analyze the influence of elastic effect on wave load of the floating structure.
