Twin Roll Tire Dynamometer

A new tire test facility which simulates tire operation on emission twin roll chassis dynamometers has been developed. This paper describes the physical characteristics as well as the test capabilities of the new Twin Roll Tire Dynamometer which includes powered and free rolling tire testing.

The facility’s primary function is to research tire behavior on twin roll dynamometers in order to determine which tire parameters are important to energy consumption. Examples of some typical tire test data obtained on this facility are also presented.
