摘要
Multi-dimension force platform(MFP) is commonly used in human balance function assessment to measure the ground reaction force and the center of pressure (COP). For improving the precision of measurement and simplification the calibration process, this paper devised a generalized load calibration device which can calibrate six axis force simultaneously. Based on the load shift principle, the true loads in every axis were determined when a generalized load was applied on the platform. After experimental verification on force plate devised by our laboratory, the calibration matrix C was calculated based on least-squares approach. The result showed that the crosstalk was kept below the thresholds of most common, commercial force platform.
