The large rotational inertia applied to a driveline component during normal driving conditions is simulated in a test stand that contains a component that driveably connects an input motor and an output motor. A computer repetitively executes an algorithm that produces a commanded torque signal which is supplied as a control signal to the motor drive of one of the electrical motors to produce an output within that motor equal to the commanded torque. The control system applies to the powertrain component under test an inertia that simulates the actual vehicle inertia. The target state of the system, when the vehicle inertia is applied, is completely defined from information known when the component being tested has substantially less inertia applied.

Computer simulated inertia for motor vehicle powertrain testing

A balancing mechanism for reducing the vibration of a piston type internal combustion engine having a crankshaft and a camshaft comprises one or more reciprocating balance weights driven by two rotating cams with at least one of said cams being driven by either said crankshaft or said camshaft.
