| 船舶海难事故严重影响人命和船舶安全，造成严重危害，所以研究船舶的破损稳性具有现实意义和实用价值。本文在选定了船舶的破损位置、破口形状及尺寸、舱室位置及舱室大小等因素下，研究受损船舶的流体运动特性和受损船舶在每一时间步长下的进水情况，利用破损船舶损坏舱室的位置、进水量等情况来预测船舶的物理行为，对破舱船舶进行时域模拟研究。首先利用STAR-CCM+对一艘标准箱型驳船模型破舱模拟研究，验证研究方法准确可行，再利用该方法对一艘渔政船进行破舱进水时域模拟研究。利用这种研究方法可对船舶破舱稳性进行计算与评估，研究结果可为有效减损及扶正提供参考，并为船舶破舱设计提供重要依据。 |

| Shipping accidents seriously affects human life and ship safety, and causes serious harm, so it has practical significance and practical value to study the stability of ship damage stability. In this paper, under the factors of the ship's damage location, shape and size of the fracture, the position of the cabin and the size of the cabin, the fluid motion characteristics of the damaged ship and the water inflow condition of the damaged ship at each time step are studied. The location of the damaged vessel and the amount of water entering the damaged ship are used to predict the physical behavior of the ship, and the time domain simulation of the damaged ship is carried out. Firstly, using STAR-CCM+ to simulate the damage of a standard box barge model, the verification method is valid and feasible, and then the time domain simulation study of a fishery vessel is carried out. This research method can be used to calculate and evaluate the damage stability of the ship. The research results can provide reference for effective damage reduction and correction, and provide an important basis for ship damage design. |
