摘要
载液船舶破损后涉及液舱进水、泄漏、晃荡等复杂水动力耦合运动问题。通过液舱破损模型试验,对其静水中的自由横摇衰减运动进行分析,研究了不同初始横倾角、不同载液率对横摇、垂荡以及舱壁压力的影响以及运动响应与压力之间的关系。通过试验发现:浅水工况(12.5%载液率)下,液舱的运动响应最为剧烈;破口一侧下沉的扰动会造成更大运动响应以及舱壁砰击压力;舱壁砰击压力的相位与液舱横摇运动相位几乎一致。
The damaged liquid carriers involve complicated hydrodynamic coupling problems such as flooding,leakage and sloshing. Through the model test, the free roll decay motion in calm water is analyzed. The effects of different initial heel angles and different liquid loading rates on roll, heave and bulkhead pressure, and the relationship between motion response and pressure are studied. The results show that under the shallow water condition(12.5% loading rate), the motion response of the tank is the most severe. The disturbance caused by the sinking of the breach side can result in relatively greater motion response and bulkhead impact. The phase of the bulkhead impact is almost the same as that of the tank rolling motion.
