Experimental Investigation of Rolling Contact

A particular case of rolling contact, that for cylinders having different elastic constants and transmitting a tangential force in the direction of rolling, was experimentally investigated. A steel cylinder, driving a rubber-covered cylinder, was instrumented for the quantitative, as well as qualitative, investigation of the action taking place in the contact area. The results indicate the extent of the locked region at the leading edge of the contact area, the development of the slip region, and the magnitude of the constant-rate slip at the trailing edge of the contact area.
