system and method for force platform calibration and calibrated force platform

摘要

Summary "force platform and calibrated force platform calibration system and method" means a method for calibrating a force platform that includes providing a force platform and applying an nxm grid to an upper force platform surface by means of a computing device. then apply known loads p to each of the upper surface grid points nxm along a z axis being perpendicular to the x and y axes and along the x and y axes. multipoint measurements are then taken at each grid point and for each known load applied along the x, y and z axes and generating six measured output signals, exact position coordinates and known load magnitude applied to each grid point. then assemble a six equation nxmxp matrix with six unknowns for each grid point and known load applied, then solve the assembled equations and derive a position and load the specific calibration matrix for each grid point. .
