摘要： A method for evaluating energy transmission from an axle through a vehicle suspension system. The methodology employs a torsional actuator to apply input energy to the vehicle in a manner that mimics the energy that is generated by the axle during the operation of the vehicle so that both the driving load and the vibration induced by gearset motion variation are simulated. Since the energy input can be quantified and monitored, the same amount of torque can be applied during each test to permit the technician to fully comprehend differences in the designs of several axles on the transmission of noise and vibration.

摘要： A method for damping torsional vibrations in a rotating shaft. The method includes coupling an actuator to a shaft; rotating the shaft; determining an amount of torsional vibration in the shaft; and controlling the actuator in response to the amount of torsional vibration and a rotational position of the shaft to damp the torsional vibration in the shaft.
