    • Abstract
  • A non-repositioning multi-component calibration system (BCS-100 in CAAA)is developed to study the calibration method for acquiring the body coordinate system coefficients matrix.The algorithm of loads transformation from the geodetic coordinate system to the body fixed coordinate system is established based on the loading method used by BCS-100.The config-uration of the loading sleeve is developed to avoid additional moment due to the deviation of the loading direction from the center line of the loading sleeve.The error resulted from the manner of displacement measure is analyzed and the method to reduce the error is proposed also.The differ-ences between the processed experimental result by using the matrix from BCS-100 and the result by using another matrix from a repositioning calibration system for the same balance TG618C is analyzed,and the validity of the calibration method expatiated in this paper can be confirmed.
