DYNAMIC EFFECT OF A FLAT WHEEL ON TRACK DEFORMATION

A series of riding tests was made to clarify dynamic effects of wheels (whose treads were set with flat spots) on the rolling stock as well as on the track at various speeds up to 200 km/h on the test run section of the New Tokaido Truck Line on December 7-11, 1963. In the present report, major test results concerning track deformation are outlined. Shock values resulting from rail bending stress and pressure between rail and sleeper grow rapidly with train speed, showing the peak at 20 to approximately 30 km/h, and thereafter up to 100 km/h, they gradually decrease.
