大型船舶比如吊装船、起重船等在装载过程中的稳定性会受到重物位置变化和海上风浪流干扰力的影响，一旦大型船舶在干扰作用力下产生幅度较大的横摇等运动时，其自身稳定性就会遭到破坏，严重时甚至会出现船舶倾覆等事故。针对大型船舶的稳性校核和控制问题，本文分别从风浪环境作用力、船舶运动模型、船体稳性恢复力矩建模等方面进行研究，并结合Matlab进行船舶稳性指标的仿真。
The stability of large ships, such as hoisting ships and crane ships, during loading will be affected by the change of the position of heavy objects and the disturbance force of wind, wave and current at sea. Once the large ships roll and other motions with large amplitude caused by the disturbance force, their own stability will be destroyed, and in serious cases, accidents such as ship capsizing will even occur. Aiming at the stability check and control of large-scale ships, this paper studies the wind and wave environmental force, ship motion model, ship stability restoring moment modeling and so on, and simulates the ship stability index with Matlab.
