Comparison and Analysis of Strain Gauge Balance Calibration Matrix Mathematical Models.
Abstract
The construction, comparison and analysis of three distinct strain gauge balance calibration matrix models with various orders of the calibration equations was conducted. The aims of the investigation were to identify the accuracy of the three different calibration matrix models and to analyse their behaviour with different data optimisation techniques. A computer program written in the C and X/Motif programming language has been developed to analyse the matrix models. Two different least squares methods and four optimisation techniques have been implemented within the software. The accuracy of each calibration model is evaluated using two statistical estimation methods. It was found that all three balance calibration models had similar behavior in terms of accuracy. The accuracy of the equation in estimating the loads experienced by the balance increases as the order of the calibration equation increases.
