Effects of SINS design parameters on mechanical dither amplitude of ring laser gyroscope

建立了单陀螺惯导系统等效二自由度模型,讨论了陀螺抖动频率随基础结构固有特性的变化规律,并利用数值试验的方法研究了基础结构与机械抖动系统的频率比、惯量比、基础结构的阻尼比以及陀螺抖动系统阻尼比对陀螺抖动幅度的影响规律。

A two-freedom model of SINS with one mechanical dither gyroscope is presented, and the change of dither frequency with the change of the support＇s eigenvalue is discussed. Moreover, by means of numerical experimentation, the effects of the ratio of the support＇s eigenvalue to dither frequency, the ratio of the support＇s inertia to mechanical dither system＇s and damp coefficient on dither amplitude of ring laser gyroscope are discussed in detail.
