摘要
以国产某型二频机抖激光陀螺为对象,采用有限元方法,求得激光陀螺各个方向上的刚度系数和耦合刚度系数,建立陀螺的抖动动力学模型,分析了陀螺的幅频特性。对动力学模型中求得的各个方向上的固有模态进行了验证,证明了激光陀螺抖动动力学模型的正确性。
According to a China＇s mechanically dithered RLG, the paper derived the stiffness coefficient and coupling stiffness coefficient by finite element method, established the dithering dynamics model, simulated and analyzed the amplitude-frequency characteristic of the RLG. The inherent mode in all directions derived in dynamics model was verified, which prove the correctness of the RLG dithered model.
