Abstract :The berthing energy and rubber fender reaction load are the most important parts in choosing the type of the rubber fender.As a typical example of Ghana some new terminal expansion project,by analyzing and calculating the absorption distribution of fender system,we changed the single energy-absorbing fender mode to multiple energy-absorbing fenders which is allowed by the standards of China and British.When the ship berthing,we used the different berthing points to analyze the adverse berthing conditions,by using the ship bow radius,fender energy absorption capacity and the corresponding deformation as the analysis of factors to determine the different points of impact fenders involved in energy absorption (The number of different fenders is also called different berthing conditions).According to the different berthing conditions,we analyzed and

calculated the energy absorption and deformation of the fender group to get the optimal rubber fender model that meets the requirements of energy absorption and wharf structure protection,so as to realize the optimal design of the fender.Key words :rubber fender;berthing energy;reaction force;absorption distribution 摘要:船舶靠泊时撞击能量和橡胶护舷的受力分析是橡胶护舷选型最重要的部分。以加纳某新集装箱码头为例,通过对橡胶护舷吸能的分配进行分析计算,将原设计单个护舷吸能模式改为中外规范允许的多个护舷吸能的模式,并以靠泊时船艏撞击点的不同来分析不利靠泊工况,以船舶船艏圆弧半径、护舷组吸能能量及对应的变形为分析因

素,确定不同撞击点时参与吸能的护舷数量(不同的吸能护舷的数量也称为不同的靠泊工况)。根据不同的靠泊工况

对护舷组的吸能和变形进行分析计算,得出满足吸能及码头结构保护的最佳橡胶护舷型号,实现对护舷的优化设计。关键词:橡胶护舷;撞击能量;护舷反力;吸能分配

May.2018护舷系统的设计是一个较复杂的过程,目前

在世界范围内还没有一本设计规范能让护舷系统

的设计标准化,大部分设计程序还是需要依赖护

舷系统专业设计人员的经验来实现。目前全世界

最主流的设计规范是国际航运协会(PIANC )出版

的“Guidelines for the Design of Fender Systems :2002

Report of Working Group 33-MARCOM ,Appendix A ,Procedure to Determine and Report the Perfor原mance of Marine Fenders ”,此外还有英国国家标准(BIS ),日本国家标准(JIS ),欧洲标准(EURO CODE )等。护舷的设计一般有4个步骤,首先是收集船舶、码头、靠岸和环境因素信息,第二是确定最大船舶靠岸动能,第三是根据码头船舶的特质分别确定护舷弹性体、前部结构和运动限制装置

(可以有多种方案),最后是根据设计合理性及材料
