TEST RESULTS BY FULL SIZE WHEEL-AXLE FATIGUE TESTING MACHINE

For the perfect solution of the problem of preventing train accidents due to axle failure, it is necessary to get an accurate grasp of mechanism of fatigue crack initiation and its propagation in wheel axle. From this standpoint, it was decided in 1964 to develop a full size wheel axle testing machine and the developed machine was set in RTRI and now, several kinds of fatigue tests have been carried out using this machine. This report describes the general performance of the machine and a few fatigue test results about old axles or new axles. The forms of wheel-seat are four kinds and the heat treatments of axles are two kinds.
