Calibration Error Analysis for Six-Axis Force Sensor Used in Docking System

The calibration error of a calibration machine will affect the precision of the six-axis force sensor directly. Aiming at the calibration machine with three force sources, calibration errors of the six-axis force sensor for docking system are analyzed to improve measurement precision. The loading position error and angle error of loading axis are researched on alternatively. The error in the calibration direction and the additional error in other directions are studied on. Analysis results will provide important reference for calibration of the six-axis force sensor.
