单动调式陀螺寻北系统及其转位方案

瞄准线稳定系统和自寻北定向系统对于坦克等陆地战车是非常重要的。文中针对目前大多数战车都装有瞄准线稳定系统的这一情况 ,在原有稳瞄平台的基础上 ,增设加速度计等相应设备 ,并加以计算机控制。由于辅加的加速度计和原系统中的陀螺仪分别可感测重力加速度和地球自转角速度 ,从而就可进行水平调平和方位的解算 ,使得系统同时具有稳定跟踪功能与寻北定向功能 ,构成组合平台。文中采用了双位置寻北解算方位角 ,着重讨论了单动调式陀螺所构成的寻北系统及其特征 ,并分析制定了转位的控制方案。仿真表明 ,该方案是可行的。

North-Finding System Based on Single Dynamic Gyroscope and Its Scheme of Moving Control

The stabilizing line of sight system and the north finding system are necessary to a vehicle used in battleground. At present, the most vehicles have loaded the stabilized platform. Under the situation, in order to reduce the cost,weight,volume of the whole system, two accelerators and other equipments are added to the stabilizing line of sight inertial platform and to contol the process with a computer instead of two independent systems. The adding accelerators can measure the acceleration of gravity and the original gyroscope can test the rotation angular velocity of the earth, so we can make the lever of the platform to horizon and get the azimuth. Therefore, the platform gains the ability of self north finding while its original abilities, stabilizing aim and tracing, are preserved at the same time, which form a integrated platform. This paper applies two positions to seek the azimuth of the vehicle, so the speed and the accurate of turning directly affect the precision and the time of the north finding. The system is analysed , the feature of north finding system with only a dynamic gyroscope and the means of turning control are studied and the importance of accuracy of turning is stressed. Finally, the simulated curve shows that the method is feasible.
