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.

Abstract: According to one aspect of the invention, a force measurement system includes a force measurement assembly, a motion base configured to displace the force measurement assembly, and an inertial compensation system configured to determine the inertial forces and/or moments resulting from the displacement of the force measurement assembly by the motion base. According to another aspect of the invention, a method for accurately determining the forces and/or moments applied to a surface of a force measurement device by a subject disposed thereon is disclosed, which includes the step of determining, by using an inertial compensation system, the inertial forces and/or moments resulting from the displacement of a force measurement assembly by a motion base. According to still another aspect of the invention, a force and/or motion measurement system having inertial compensation includes a motion acquisition system having a plurality of motion sensing devices configured to capture a subject's movement.
