散装谷物稳性计算软件的开发

根据国际海事组织现行的规范,分析了专用散装谷物舱室的稳性校核方法 ,并利用C++开发软件进行谷物稳性校核,软件开发在已有的船舶初步设计平台软件中进行。作为谷物稳性计算的基,该平台软件已具有舱室布置等功能。通过对谷物舱室在各个装载情况下的倾侧力矩以及对实船谷物舱室的计算,最终结果均表明软件的准确度较高,且与主流计算软件(NAPA)的结果基本吻合。

Development of software for bulk grain stability calculation

According to the current rules of IMO ,this paper analyzes the methods for stability verification of bulk grain cabin,and carries out the stability verification of bulk grain by using C＋＋software. The software is developed based on an existing platform during the ship preliminary design. As basis of stability calculation of grain ,this software is already enabled with the interior arranging functions. It calculates the heel moment of the grain cabin under each loading condition and grain cabin for the full-scale ships. The results show great accuracy ,and are consistent with the calculation results of the prevailing NAPA software.
