摘　　要：当载液货船在海上航行时,风、浪、流等环境载荷的作用会引起部分装载液舱产生液体晃荡现象。液舱晃荡不仅会对船舶安全带来一定的潜在风险,而且还会对海洋生态环境造成严重的威胁。本文针对不同装载率的双液舱自由衰减运动进行研究,通过分析双液舱在衰减运动过程中,液舱角速度变化情况和液舱壁面的抨击压力以及自由液面的波高变化,探究双液舱自由衰减运动的机理和规律,可为载液货船的设计和制造提供一定的依据。When liquid cargo carriers navigate in the sea,external loads from waves,winds or currents will lead to the phenomenon of liquid sloshing,which is a potential hazard not only for the ship itself but also a threat for the marine environment and ecology.In this study,double partially-filled liquid tanks are adopted to investigate the effects of liquid sloshing on the free attenuation motion of the liquid cargo carriers with different loading rates.The impact force on the wall of tank,the maximum free surface displacement as well as the variation of angular velocity are analyzed during the attenuation motion,so as to provide some reference for the design and manufacture of liquid cargo carriers.
