摘　　要：基于700~4200 TEU等5种典型的集装箱船,对《CCS-2012》规范和《CCS-2017》规范给出的2种用于集装箱系固计算的横向加速度计算方法进行对比,计算5种船型不同纵向位置的横向加速度及可实现的最大堆重,基于4200 TEU集装箱船讨论船型参数对《CCS-2017》计算结果的影响,结果表明,与《CCS-2012》相比,《CCS-2017》对船舶尺度大于1900 TEU级的中、大型集装箱船的系固设计有利,但将给船舶尺度小于1900 TEU级的小型集装箱船的系固设计带来不利影响;对于船舶尺度大于1900 TEU级的集装箱船,随着船舶尺度的增加,《CCS-2017》的优势越明显;方形系数、航速、船宽对《CCS-2017》的横向加速度及最大堆重计算结果存在一定影响,其中船宽是最主要的影响因素。Based on five typical container ships in the scope of 700 TEU to 4200 TEU,two methods for calculating the transversal acceleration given by CCS-2012 rules and CCS-2017 rules respectively were comparatively studied.The transversal acceleration and the maximum achievable stack weight were calculated for different longitudinal positions of the five ships.The influence of ship parameters upon the results of CCS-2017 method was discussed based on the 4200 TEU ship.The results showed that compared with the CCS-2012 method,the CCS-2017 method has advantages to container securing design of the medium and large size container ships which size is greater than 1900 TEU class,but would bring adverse influence to container securing design of the small size container vessels which size is smaller than 1900 TEU class.For vessels larger than 1900 TEU class,advantages of the CCS-2017 method is more distinct when the ship dimension increasing.The block coefficient,speed and ship breadth impact the result of the transversal acceleration and the maximum achievable stack weight in CCS-2017 method,in which the ship breadth is the most important impact factor.
