摘要
晃荡载荷作用下船体结构的局部强度校核,对保证LNG船营运安全非常重要。由于将液舱晃荡载荷等效到船体结构上可以极大程度提高局部强度校核的工作效率,以缓冲系数反映绝缘系统的缓冲效应,针对三艘LNG船展开分析,在对简化建模方法进一步讨论的基础上,通过计算得到了目标船绝缘系统在横摇和纵摇工况下的缓冲系数,研究成果可为相似规格,相近结构的LNG船晃荡强度校核提供参考。
Considering the operation security of LNG tank, it is very important to check the local strength of the LNG tanks under the action of sloshing load. As the efficiency of the operation can be highly improved by equaling the sloshing load to hull structure, through using the buffer coefficient to react the buffering effect, it is possible to do an analysis of the system of three different LNG tanks. With the further simplified model, buffer coefficient of the rolling and pitching condition can be obtained through calculation. The results can be referred if the LNG tank has similar specification and hull structure.
