Abstract:

The experimental apparatus incorporated a 1020 steel rider on a rotating concrete wheel. The tests conducted were limited to contact pressures of 5, 7 12, and 10 psi, and velocities less than 50 mph. It was found tha the coefficient of friction was independent of load, but decreased with increasing velocity. For all contact pressures, the wear of the steel compared to the wear of the concrete was approximately the same. However, wear of each constituent did increase as the contact pressure was increased. Finally, the heat conducted into the steel decreased with increasing velocity while the heat conducted into the concrete increased.
