| 中文摘要: |
| 沿海渔船的船型瘦小，对于动稳性的变化较为敏感，船体破损后失稳会产生严重的危害，因而近海作业的沿海渔船破舱稳性研究有比较实际的应用价值．运用CFD软件STAR-CCM+，对一艘28.8 m长、作业区域为渤海的养殖看护船，进行横浪条件下瞬时非对称进水过程的时域模拟，得到该船破舱进水过程中船舶的六自由度变化以及压力分布．对比该船在3种海况下破损后的物理行为发现，非对称舱进水会在波浪作用下带动船舶产生不同程度的艏摇运动，促使破损船由横波运动向纵波运动转变，基于破损后的运动响应，可以对渔船的舱室分布及对破舱事故后的操纵及减损提供参考意见． |
| 英文摘要: |
| Coastal fishing boats are thin and sensitive to changes in dynamic stability. The hull instability will cause serious damage after the hull is damaged. Therefore, the study of the stability of the damaged cabin of coastal fishing boats in offshore operations has more practical application value. CFD software STAR-CCM+ is used to simulate the time domain of the instantaneous asymmetrical water inflow process of a 28.8 m breeding care boat in Bohai Sea under the transverse wave conditions, and the variation of the boat′s six degrees of freedom and pressure distribution during the cabin flooding process are obtained. By comparing the physical behavior of the damaged boat under three sea conditions, it is found that the water in the asymmetric cabin will drive the boat to roll in different degrees under the action of waves, which makes the damaged boat change from shear wave motion to longitudinal wave motion. Based on the motion response after the damage, some suggestions on the cabin distribution of the fishing boat and handling and damage reduction after the damaged cabin accident can be put forward. |
