舰船破损进水的实时数值仿真

Real-time Numerical Simulation of Flooding of Damaged Vessels

在岸基损管堵漏训练中,需要实时计算出堵漏训练舱的进水速度、浮态、稳性随时间的变化情况。建立任意姿态条件下任意破口流速的计算模型,提出了内外液面到破口最低点距离的计算方法,并得出了单舱自由液面惯性矩的计算公式。通过软件编程,对进水速度、浮态与稳性的关系进行了可视化模拟,实现了船舱进水过程的快速实时仿真,为计算堵漏训练舱进水状态提供了重要支撑。

Real-time calculation of the temporal parameters of inflow rate, floating, stability of damage control wet trainer is necessary. The calculating method of inflow rate through arbitrary damage openings at arbitrary behaviour is developed,＂ the calculating model of the distance between internal^external surface and damage openings is established,＂ the calculating method of the moment of inertia of free surface is developed. The visual simulation of the relation between inflow and behaviour is performed by software. The fast real-time simulation of flooding that is designed to support a calculation of damage control wet trainer＇s motion is established.
