摘　　要：惯性仿真转台动态特性直接制约着惯性器件的标定精度,该文通过设置惯性仿真转台3个转动框架的摇摆幅度和频率,研究各旋转框在独立摇摆工作条件下所对应的角位置、角速度和加速度的理论输出与实际输出的获取方法并建立两者间的误差曲线。转台测试结果表明,该测试方法可有效获取实验室三轴惯性仿真转台的动态误差特性,且转台高频抖动噪声是影响惯性器件标定效果的主要因素。The calibration accuracy of inertial device is determined by the dynamic characteristic of inertial simulation turntable.By setting up the swing amplitude and frequency of the three turning frameworks in the inertial simulation turntable,the method for obtaining the theory and practical output of angular position,angular rate and acceleration of each turning framework under independent swing is studied,and the error curve between theory and practice is calculated.The turntable testing results show that the dynamic error characteristic of three-axis inertial simulation turntable can be obtained by the proposed testing method and the high frequency dither noise is the main factor of influencing the calibration accuracy of inertial device.
