论文主要探讨了单体复合船型破损后的浮态稳性变化、破损舱室液舱晃荡效应等因素对破损后单体复合船型运动和波浪载荷的影响。采用面元法求解液舱晃荡运动的附加质量，分析液舱内流体晃荡运动的共振现象以及流体粘性阻尼系数对液舱晃荡载荷的影响；推导了破损后非正浮状态下船体质量力和静水恢复力公式，使用三维势流理论求解发生的船体运动和破损舱室内液舱晃荡运动的流体载荷，建立破损后船舶运动方程并求解，研究破损后浮态、稳性以及液舱晃荡效应对六自由度运动和波浪载荷的影响。研究表明，破损后浮态、稳性、液舱晃荡等对单体复合船运动及波浪载荷均会产生影响。

Motion performance of damaged hybrid monohull is researched,including influence of floating condition variety and liquid tank sloshing. Added mass of sloshing is solved by panel method. Resonance phenomenon and influence of fluid viscous damping on sloshing load is analyzed. The formula of mass force and hydrostatic restoring force under non-upright floating condition is derived and the liquid load of hull motion and sloshing is solved with three dimensional potential flow theory. Based on these methods, damaged ship motion equation is established. By comparison of motion and wave load response before and after damage,effects of floating condition,stability and sloshing on the motion after damage are analyzed. It is <br> indicated that after damaged the floating condition, stability, and liquid tank sloshing would influence the motion and wave loads of hybrid monohull.
