中文摘要:

船舶海难事故严重影响人员和船舶安全,所以研究船舶稳性具有现实意义和实用价值.在选定了船舶的破损位置、破口形状及尺寸、舱室位置及大小等因素下,研究受损船舶的流体运动特性和在每一时间步长下的进水情况,利用破舱位置、进水量等信息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进行模拟研究,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.

英文摘要:

Shipping accidents seriously affect human life and ship safety, so it has practical significance and practical value to study the damage stability of ship. Considering the factors of the ship′s damage location, the shape and size of the fracture, the position and size of the cabin, the fluid motion characteristics of the damaged ship and the water inflow at each time step are studied. The location of the damaged cabin 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 conducted. Firstly, by using STAR\|CCM+ to simulate the damage of a standard box barge model, the research method is proved to be valid and feasible. Then the time domain simulation study of water inflow of a damaged fishery administration ship is carried out by the proposed method. This research method can be used to calculate and evaluate the damage stability of ship. The research results can provide reference for effective damage reduction and correction, and provide an important basis for ship damage design.
