Abstract
A chassis dynamometer includes a frame, a roll set for engaging the wheels of a motor vehicle and an eddy current brake/inertia simulating unit with a rotor having ferrous metal rotor wheel rotatably mounted on the frame and a plurality of stationary field coils. The rotor has a rotational mass within the range of 70 to 90% of the base or minimum inertia of the dynamometer. A force transducer and a speed encoder provide a measure of the force applied to the roll by the wheel and the speed of the roll, respectively. A controller, in response to the roll speed and force applied to the roll controls the current to the field coils in accordance with a selected simulated inertia and road load for the vehicle.
