摘要

采用附加质量模型,对工程船的靠泊碰撞进行有限元数值模拟。研究了停泊船及橡胶护舷在靠泊船冲击力下的响应。根据最大靠泊力、吸能比、靠泊极限速度及对船体的冲击响应等指标分析了方型、半圆型及混合型橡胶护舷的表现,从船体结构安全性角度出发对护舷结构的型式选取提出建议。

Abstract

Numerical simulation of the berthing process between two engineering ships by an added mass model was carried out. The response of the struck ship as well as the rubber fender under the berthing impact was studied. Based on such indexes as the maximum berthing force, the energy absorption ratio, the ultimate allowable berthing speed etc, performance of three types of rubber fender was compared and analyzed. Advice for the selection of rubber fenders considering the vessel’s structural safety is finally proposed.
