Abstract
The invention provides a system and method for measuring tire forces wherein the force contributions of the test machine may be separated from the force contributions of the tire. The invention achieves the separation of the forces by equipping the test station with a plurality of accelerometers that allow the forces and the moments of the components of the measurement station to be calculated and accounted for in the overall force measurement. In one embodiment, the test station uses a slip ring disposed between the rotating rotor to which the tire is mounted and the stationary bearing housing to allow data to be easily gathered from the accelerometers mounted on the rotor. The slip ring also allows tires to be easily mounted and dismounted.
