    Abstract: A force measurement system and a motion base used therein is disclosed herein. The force measurement system includes a force measurement assembly configured to receive a subject, a motion base for displacing the force measurement assembly, and one or more data processing devices operatively coupled to the force measurement assembly and an actuation system of the motion base. The motion base includes a support structure; a displaceable carriage coupled to the force measurement assembly; and an actuation system, the actuation system including one or more actuators operatively coupling the displaceable carriage to the support structure, the one or more actuators configured to displace the displaceable carriage with the force measurement assembly relative to the support structure, the displaceable carriage being suspended below a portion of the support structure.

    Abstract: A motion base for displacing a force measurement assembly is disclosed herein. The motion base includes a base assembly; a support structure configured to be coupled to the force measurement assembly; a rotatable coupling device, the rotatable coupling device rotatably coupling the support structure to the base assembly; and an actuation system, the actuation system including one or more actuators operatively coupled to the support structure, the one or more actuators configured to displace the support structure relative to the base assembly. In one or more embodiments, greater than 50% of the weight of the support structure is supported by the rotatable coupling device. Also, in one or more embodiments, the motion base may be used for displacing objects other than a force measurement assembly, such as for displacing a flight simulator or a virtual reality simulator.

    Abstract: A swivel foot assembly for a force plate or balance plate is disclosed herein. The swivel foot assembly includes a foot attachment component including a stem portion and a body portion, the stem portion of the foot attachment component configured to be attached to a force plate or balance plate; and a foot base component including a receptacle for receiving the body portion of the foot attachment component, the foot base component configured to be disposed on a support surface. The swivel foot assembly is configured to accommodate an uneven support surface on which a force plate or balance plate is disposed so that a force measurement accuracy of the force plate or balance plate is not adversely affected by stresses resulting from the uneven support surface.

    Abstract: A force measurement system includes a plurality of force measurement assemblies arranged in a loop configuration, the plurality of force measurement assemblies configured to be displaced around a continuous path of movement such that a particular one of the plurality of force measurement assemblies that is disposed underneath a subject varies over time. Each of the plurality of force measurement assemblies includes a top surface for receiving at least one portion of the body of the subject; and at least one force transducer, the at least one force transducer configured to sense one or more measured quantities and output one or more signals that are representative of forces and/or moments being applied to the top surface of the force measurement assembly by the subject. The force measurement system may additionally comprise a data processing device operatively coupled to each of the force transducers of each of the force measurement assemblies.
