吊放声呐拖曳系统带速回收动力学建模与仿真

Research on dynamics modeling and simulation of dipping sonar towing system with speed recovery

吊放声呐是航空反潜重要的搜潜设备,吊放声呐采用带速回收的模式可减少作业时间,有效提高反潜作战效能。带速回收过程吊放电缆所受最大拉力、吊放电缆的偏转角以及水下分机的偏角对吊放声呐系统设计影响较大。建立带速回收过程的动力学模型,根据风洞试验结果,对模型进行标定完善,并对吊放声呐的带速回收过程进行仿真。仿真结果表明,带速回收过程吊放电缆最大拉力基本保持稳定,吊放电缆偏转角与水下分机偏转角变化趋势一致,角度相差不大,同时风速对吊放电缆最大拉力影响很小,在一定范围内风速与吊放电缆偏转角负相关,有利于回收。

The dipping sonar adopts the mode of speed recovery to reduce the operation time and effectively improve the anti-submarine combat effectiveness.The maximum tension of the lifting cable,the deflection angle of the lifting cable and the deflection angle of the underwater extension have a great influence on the design of the lifting sonar system.In this paper,taking a certain type of dipping sonar as an example,the dynamic model of the speed recovery process is established.According to the wind tunnel test results,the model is calibrated and improved.Based on the above,the speed recovery process of the dipping sonar is simulated.The simulation results show that,the maximum tension of the lifting cable during the speed recovery process is basically stable.The deflection angle of the lifting d cable is consistent with the deflection angle of the underwater extension,and the angle is not much different.At the same time,the wind speed has little effect on the maximum tension of the suspended cable.Within a certain range,the wind speed is negatively correlated with the deflection angle of the suspended cable,which is conducive to recovery.The research content provides reference for the in-depth study of the subsequent speed recovery characteristics and the application of the future speed recovery mode.
