摘　　要：比较原船方案和优化方案在两种装载状态下固定起吊7500t时的数据,发现了一些问题。从而进一步分析了探讨数值分析法中所采用的优化原则的局限性。通过建立简单的数学模型,运用相关的数学软件,分析总结出压载舱分舱时的规律。比较分析几种典型的回转起吊的工况,总结出回转起吊时的一些规律。最后,归纳出如何优化设计大型起重船的压载舱。The limitation of optimization principles which are applied in the numerical analysis method has been further discussed.By comparing with the data of fixed lifting 7500 tons of cargo under two loading conditions,several problems existing in the original program and optimized program have been found.By establishing mathematical model and utilizing related software,some principles about ballast tank subdivision are summarized.They are applied and analyzed in several typical working conditions about rotary lifting and then a few rules are summed up.Finally,it is concluded how to optimize the design of ballast tanks for a large floating crane.
