摘要
以三轴机械抖动激光陀螺捷联惯导系统为研究对象,利用数值仿真方法,详细讨论了静态环境条件下圆锥运动的形成机理以及机械抖动激光陀螺的惯性参数对惯导系统圆锥运动的影响规律。研究认为,在静态环境条件下,惯导系统的质量分布特性不是产生圆锥运动的原因;惯导系统在静态环境条件下出现的圆锥运动是由于机械抖动陀螺抖动机构的三类不平衡——静不平衡、动不平衡和配不平衡造成的。
Taking three-axis dithered laser SINS as research object and using numerical simulation method, the formation mechanism of conning motion under static environment condition and the affection of the gyro＇s inertial parameters on its conning motion were discussed. It is found that the mass distribution characteristics of SINS are not the causation of coning motion. Instead it is the three kinds of unbalances （i.e. static unbalance, dynamic unbalance and counter unbalance） in dithering mechanism that cause the coning motion in static environment condition.
