Spinvision: A New Look at Dynamic Tire Temperature 700473

Recently, a unique image derotator has been developed which will permit a continuous stationary view of a tire actually moving at very high angular velocities. This device, called Spinvision, has been combined with a special infrared camera and monitor which allows engineers to observe instantaneous change in the heat patterns on the surface of a rotating tire. With conical mirrors around the tire, almost the complete surface may be studied, under loaded conditions, at speeds in excess of 150 mph.
The intended application of this equipment is to locate potential faults in tires, while they are originating, instead of depending upon post-failure examination for analysis. It may also be possible to explore the relationship between heat patterns and tire wear, and tire uniformity.
