1·The coordinate system for three axes frame of simulator is defined, the dynamic analysis of simulator frame system is analyzed, the kinematics and kinetic models have been built.
对转台三个框架系统的坐标系进行了定义，对转台框架系统的动力学进行了分析，建立了三轴转台框架运动的运动学和动力学模型。
2·On the basis, the ratio of quadrature error and sense signal are induced when the the principal axes of elasticity of outer-frame and inner-frame rotates a little Angle separately.
在此基础上，利用弹性主轴原理，推导了内外框弹性主轴偏转产生正交信号与敏感信号的比值表达式。
