Abstract
A method for calibrating a force platform includes, providing a force platform and applying an n×m grid on a top surface of the force platform via a computing device. Next, applying p known loads on each of the n×m grid points of the top surface along a Z-axis being perpendicular to the X and Y axes and along the X and Y axes. Next, taking multipoint measurements at each grid point and for each applied known load along the X, Y and Z axes and generating six measured output signals, exact position coordinates and applied known load magnitude for each grid point. Next, assembling an array of n×m×p of six equations with six unknown for each grid point and applied known load and then solving the assembled equations and deriving a position and load specific calibration matrix for each grid point.
