基于旋回机动的潜艇艉升降舵卡挽回仿真研究

Simulation of Retrieving Stern Rudder-jamming Based on Submarine Cycle Movement

艉升降舵卡下潜舵是潜艇最危险的一种舵卡形式,根据潜艇水下旋回机动产生的耦合水动力及其引起的潜浮运动特性,推导出不同航速条件下利用潜艇旋回机动可挽回的艉升降舵卡下潜舵舵角的计算方法,并通过六自由度潜艇运动仿真与控制研究平台对计算结果进行了仿真验证,仿真结果表明在一定航速范围内采用操方向舵旋回机动对于挽回艉升降舵卡下潜舵产生的首倾下潜趋势具有显著效果,从而验证了论文提出的计算方法的有效性。

The stern rudder-jamming during diving is one of the most dangerous rudder-jamming.According to the coupling hydrodynamic and the diving motion characteristics by the submarine cycle movement,the computing method of the rudder angle retrieved by the submarine cycle movement in the case of the stern rudder-jamming is deducted.And through the six-degree-of-freedom submarine movement simulation and the control research platform the result is verified.The simulation results show that the effect of operating course rudder to retrieve stern rudder-jamming in the scope of speed is very significant.And it verifies the effectiveness of computing method.
