Development and Evaluation of Calibration Procedure for a Force-Moment Balance Using Design of Experiments

Abstract To measure the aerodynamic and hydrodynamic forces and moments acting on scaled models in water and wind tunnel tests, multi-component strain gauge force and moment balance are usually used. Their performance and accuracy largely depends on the rig and calibration method, including the load table (design matrix) and analysis of experimental data. In this article, for the calibration of a six-component balance, a calibration procedure using the Box-Behnken design (BBD) of experiments was developed. In the suggested design matrix, in addition to all possible combinations of the two-comp...
