基于外差激光干涉法的三轴向振动绝对校准方法研究
Research on the Method of the Triaxial Primary Vibration Calibration Using the Heterodyne Interferometry
摘要
Abstract
Compared with the one-axial vibration excitation in the traditional calibration method,the triaxial standard vibration exciter can simulate the actual application environment of the calibrated accelerometer.The spatial response characteristic of the accelerometer can be obtained by using the triaxial standard vibration exciter to realize the accurate calibration of the accelerometer.The sensitivity matrix model of the triaxial accelerometer was proposed which used the bandpass based on heterodyne interferometry triaxial primary vibration calibration method and the theory of the acceleration vector.This method realizes the calibration of the accelerometer by calculating its sensitivity matrix.The experimental results show that this method can simultaneously realize the high precise calibration of the principal and the transverse sensitivities of the triaxial accelerometer,and this method can effectively reduce the calibration time and the error caused by the repetitive installations.关键词
