近冰面航行潜体受力及操纵仿真研究

Simulation research on submarines force and maneuvering during sailing near the ice layer

冰层可以为潜体提供良好的隐蔽性,为潜体作战效能发挥提供极大帮助。研究潜体在冰层下航行时的受力及操纵方法,可以为潜体更好地履行使命任务提供有力支撑。以美国SUBOFF潜艇模型为研究对象,采用STAR-CCM+流体计算软件,对不同航速下的潜体近冰面运动进行数值计算分析,计算潜体受力及力矩。将潜体所受力及力矩与潜体空间六自由度方程结合,模拟潜体近冰面航行运动趋势,给出操纵方法。研究表明,近冰面航行会影响潜体航行深度及姿态保持,及时采用降速、首尾舵操舵、纵倾平衡水舱调水等操纵措施可有效控制潜体航行深度及姿态,避免触冰情况发生。

The ice layer can provide good invisibility to submarine and great help for submarine’s combat effectiveness.The research on the forces and maneuvering methods of the submarine sailing under the ice layer can provide strong support for the submarine to fulfill its mission.The SUBOFF model is taken as the research object by STAR-CCM+software.The submarine movement near the ice layer at different speeds is numerically calculated and analyzed.By combining the force and moment of the submarine with the six degrees of freedom equation,the motion trend of the submarine near the ice layer is simulated and the maneuvering methods is given.The research shows that:Sailing near the ice layer will affect the depth and attitude of the submarine.Timely use of steering,reducing speed and water transferring by balancing tank can effectively control the submarine navigation attitude and depth to avoid the submarine crashing the ice layer.
