Research on Three-Position Calibration Method for the Installation Error of Inclinometer with Two-Axis Gravity Accelerometer

Abstract:

At present,The installation error calibration of gravity accelerometer for the automatic vertical drilling tools is complex and difficult . For this,the paper presents three-position calibration method for the installation error of inclinometer with two-axis gravity accelerometer. The method is based on the equation about actual attitude angle of the inclinometer, installation error angular of two-axis gravity accelerometer and output voltage. The voltage value of the three position is measured, and iterative calculation with MATLAB is used to obtain the installation error angle. The results of simulation prove that this method can meet the requirements of installation error angle calibration of drilling tools , the calibration error is less than 1.5%.
