为了实现线加速度计的动态校准,对应线加速度计不同的量程范围,有着不同的实现方法和相应的校准设备。文中介绍了在重力场范围内所用的倾斜轴转台校准方法、高于1g范围所用的双离心机校准方法和实现微加速度动态校准的数学摆台方法,介绍了各种校准设备的组成和原理,推导了其加速度数学模型,对校准设备所复现加速度的幅值不确定度进行了分析,通过上述校准设备,可实现线加速度计在5×10⁻⁷~700m/s²量程范围内的动态校准。

In order to achieve dynamic calibration of linear accelerometer, different implementation and calibration equipment will be needed for different range. The paper describes tilt axis table calibration method in gravitational field, the double turntable centrifuge calibration method above the range of 1g and the mathematical pendulum device calibration method under micro acceleration, introduces constitution and principles of various calibration devices, analyses measurement uncertainty of acceleration amplitude. It can be achieved dynamic calibration of linear accelerometer at 5×10⁻⁷~700 m/s² range by above calibration devices.
