对于集装箱船结构评估中加速度公式所需重心位置进行研究。以10艘集装箱船为研究对象,选取规范校核的典型装载工况,参照《散货船和油船共同结构规范》中的公式开展重心位置对比。研究发现,采用《散货船和油船共同结构规范》中的公式所得结果与实际值相差较大,该公式不适用于集装箱船。在此基础上,中国船级社在其《集装箱船结构规范》中提出一种新的集装箱船重心位置估算公式。另选5艘集装箱船,通过将采用该估算公式所得结果与实际值相对比,验证该估算公式合理、实用。 |

Abstract: |
A research is carried out on the position of gravity center required for the acceleration formula in the structural evaluation of container ships. 10 container ships are taken as the research object to compare the position of gravity center with the typical loading conditions for standard verification according to the formula in the Code for the Common Structure of Bulk Carriers and Oil Tankers. The research has found that the formula values of the Code for the Common Structure of Bulk Carriers and Oil Tankers differ significantly from the actual values and are not applicable to container ships. On this basis, China Classification Society (CCS) proposed a new formula for estimating the position of gravity center of container ships in its Structural Specification for Container Ships. Another 5 container ships are selected to verify the rationality and practicality of the estimation formula by comparing the results obtained using the formula with the actual values, which has a satisfied result. |
