甲板桁材对谷物稳性的影响

The Influence of Deck Girder on Grain Stability

船舶在营运过程中装载散装谷物时,稳性相关要求与其他液货及固体货物有所不同。通过采取定义散货船中谷物空间有甲板桁材与无甲板桁材两种定义方法来计算谷物空间与谷物体积倾侧矩,通过谷物体积倾侧矩来判定谷物稳性计算数值。同时利用NAPA软件来进行校核计算,通过计算结果分析得出甲板桁材对谷物稳性的影响。

While it loads bulk grain during the operation, the ship＇s relevant requirements of stability are different from other liquid cargo or sohd cargo. The grain space and grain volume heeling moment are calculated through the two defining methods of having deck girder and having no deck girder in the bulk cargo ship＇s grain space. The grain stability numerical result is determined by grain volume heeling moment. At the same time, the researcher checks calculation using NAPA software, and analyzes the influence of deck girder on grain stability through the numerical result.
