Abstract:
1. A system for simulating torque transmission by a coupler, through which torque is transmitted between an engine and a transmission in the driveline of a motor vehicle, comprising: a torque generator that produces torque output signals having amplitude and frequency; a transmission; a signal generator driveably coupled to the torque generator and the transmission, for producing dampened variable torque output signals in response to the torque output signal produced by the torque generator and applying the dampened torque output signals to the transmission; multiple analyzers, each analyzer located at a discrete vehicle location, and measuring at said vehicle location a transient response induced by torque transmitted to the transmission by the signal generator; and a controller communicating with the torque generator, at least one analyzer and the signal generator, for commanding a frequency response from the signal generator to the torque signal produced by the torque generator, said frequency response simulating the amplitude and frequency of torque transients produced by the engine and transmitted to the transmission.
