Abstract

Abstract: Under moving base condition，the attitude angle of the inertial attitude measurement equipment is transmitted by optical equipment such as photoelectric collimation theodolite.In order to realize the high-precision transmission,the attitude relationship between inertial attitude measurement equipment and attitude transmission equipment needs to be calibrated.Under the condition of dynamic base,the photoelectric collimation theodolite measure the reference cube mirror of the inertial attitude measurement equipment.The synchronous data collector is used to synchronously collect data from the inertial attitude measurement equipment,servo stability platform and photoelectric collimation theodolite,and establishes the transfer equation system according to the coordinate conversion of the attitude angle,and realizes the dynamic calibration of the attitude relationship between the inertial attitude measurement equipment and transmission equipment by solving the unknown parameters in the transmission equipment.The inertial attitude measurement equipment and the transmission equipment are used to verify the feasibility of the dynamic calibration method.

Key words: Moving base, Attitude angle, Calibration method

According to the theory of Newton′s Third Law, the calibration device is researched and designed to calibrate the bolt tensioners. The measurement error and repeatability analysis and uncertainty evaluation show the linearity is good. Considering the measurement error is within ±1%, which meets the calibration requirements for bolt tensioners, the designed calibration device is capable to carry out the calibration work for bolt tensioners.
