| 摘 要： | 准确地确定出船舶系泊时的撞击载荷, 对船舶及海洋平台的强度研究都是极其重要的. 提出了通过能量原理和有限元分析确定系泊撞击载荷的方法. 碰撞时, 动能和变形能满足能量守恒, 动能是包括附连水质量在内的船体总动能, 此动能在撞击时转化为变形能, 根据变形能与载荷的关系, 求出碰撞载荷. 通过具有碰撞载荷理论解的梁的验证, 表明该方法是完全可行的. 为实际工程提供了确定护舷撞击力的理论依据和计算方法.

| Abstract: | It is extremely important to accurately determine the ship mooring collision load in considering ship and offshore platform's strength.This paper proposes a method to determine the ship mooring collision load with energy principle and the finite element method.In collision,the impact kinetic energy and the deformation energy are considered in the energy conservation law.The kinetic energy refers to the ship's kinetic energy including the additional water mass.It is transformed into the deformation energy wh... |
