【摘要】 建立描述晃荡条件下液货舱的运动数学模型,对薄膜型液舱在晃荡条件下的受力情况进行研究分析.通过与实验结果的对照,验证了模型的正确性.针对晃荡周期这个主要影响因素,研究薄膜型液舱的受力和内部波形变化等,从而确定所研究液舱的充满度限制条件;研究新的薄膜型液舱型式下对晃荡的敏感性程度,得到双列结构的液舱有效地降低了晃荡的冲击影响,有利于LNG船的安全运行.更多还原

【Abstract】 The forces research on membrane tank under sloshing has a great significance on LNG transportation.This paper establishes the numerical model of LNG tank under sloshing,and studies the forces on tanks.With the comparison of the experiment results,it shows the model is correct.The forces and wave forms are studied,which determines the fill level in certain sloshing period.The sensitivity extent about new LNG membrane tank type is studied also,and the double-row structure is found to reduce sloshing impacts,which is good for safe shipping.更多还原
