摘　　要：本文应用整船三维有限元方法，分析了船体在波浪中航行时受弯扭联合作用下的结构响应，船体所受的联合载荷包括静水弯矩、垂向波浪弯矩、水平波浪弯矩、扭矩及相应的剪力。通过节点力转换的方法，将船体外表面所受的海水压力转化到有限元节点上。通过节点力平衡的处理，将船体所受的联合载荷和重力及惯性力调整到与其所受的三向矩及相应的剪力相平衡。In this paper, the response of ship structure under combined loads is analyzed by using 3-D overallstructure Finite Element Method. The hydro-static bending moment, wave vertical bending moment, wave horizontal bending moment, torsional moment and the corresponding shear forces are all considered. The sea-pressuredistributing on ship hull is translated into forces acting on the finite element nodes. The combined loads includingthe gravity and inertia forces are adjusted to balance with the 3-direction bending moments and the shear forces.
