Abstract
A force measurement system having inertial compensation includes a force measurement assembly with at least one accelerometer configured to measure the acceleration thereof. According to one aspect of the invention, the force measurement system additionally includes at least one angular velocity sensor configured to measure the angular velocity of the force measurement assembly. According to another aspect of the invention, the force measurement system additionally includes a data processing device with a computer-readable medium loaded thereon that is configured to execute a calibration procedure for determining the inertial parameters of the force measurement assembly by utilizing the measured acceleration of the force measurement assembly while the force measurement assembly is subjected to a plurality of applied linear and/or rotational motion profiles. According to still another aspect of the invention, the at least one accelerometer is disposed on the force transducer.
