摘　　要：针对大型起重船压载舱的特点,提出了数值分析法的数学模型和优化原则.以7500t全回转起重船为研究对象,运用数值分析法对其压载舱进行具体的优化设计.选取四种典型的工况,评价压载舱工作时的各个参数指标,比较原压载舱和优化后的效果,从而得出数值分析法可以作为压载舱优化设计的参考方法.In view of the characteristics of ballast tanks of large floating crane, mathematical model and optimization principles have been proposed for the numerical analysis method Selecting 7500t revolving derrick barge for study, the concrete optimal design of ballast tanks has been carried out with the help of numerical analysis method Choosing four （ypical operating conditions, the effectiveness of optimized ballast tanks has been compared with the original ones in several assessment indicators. As a result, it can be concluded that the numerical analysis method can work as a reference method in optimal design of ballast tanks.
