Force measurement system

A force measurement system, comprising:

• a force measurement assembly including a plurality of load transducers spaced apart from one another, each of the plurality of load transducers including:
• a load transducer frame portion, the load transducer frame portion including a first transducer beam section and a second transducer beam section, the first transducer beam section being connected to a middle portion of the second transducer beam section, and the load transducer frame portion configured to receive a load that is applied to the load transducer;
• and
• a plurality of deformation sensing elements disposed on the load transducer frame portion, a first one of the plurality of deformation sensing elements being sensitive to a first force component of the load and outputting a first output signal representative of the first force component of the load, and a second one of the plurality of deformation sensing elements being sensitive to a second force component of the load and/or a third force component of the load and outputting a second output signal representative of the second force component of the load and/or the third force component of the load;
• and
• a data processing device operatively coupled to the plurality of deformation sensing elements of the plurality of load transducers, the data processing device configured to receive the first and second output signals from the plurality of deformation sensing elements of the plurality of load transducers, and the data processing device further configured to determine a first output force from the first output signal and a second output force and/or a third output force from the second output signal;
• wherein the first output force comprises a vertical output force, the second output force comprises a first shear output force in a first coordinate axis direction, and the third output force comprises a second shear output force in a second coordinate axis direction that is perpendicular to the first coordinate axis direction of the first shear output force;
• wherein each of the plurality of load transducers of the force measurement assembly is diagonally arranged relative to the first coordinate axis direction of the first shear output force and the second coordinate axis direction of the second shear output force such that:
• when a first shear force in the first coordinate axis direction is applied to the force measurement assembly, a summation of the second output signals from the plurality of deformation sensing elements of the plurality of load transducers by the data processing device produces a first shear force output value above a measurement threshold in the first coordinate axis direction, but generally cancels out in the second coordinate axis direction;
• and
• when a second shear force in the second coordinate axis direction is applied to the force measurement assembly, a summation of the second output signals from the plurality of deformation sensing elements of the plurality of load transducers by the data processing device produces a second shear force output value above a measurement threshold in the second coordinate axis direction, but generally cancels out in the first coordinate axis direction.
