In recently, rail deteriorations -rolling contact fatigue, wear, etc- arise as hot issue of track maintenance by speed increasing of railway. And the relative importance of the rail maintenance in concrete track, which is adopted as a track system for 2nd phase of Kyung-Bu and Ho-Nam high speed line, will be increased much more. Furthermore the rail maintenance trouble was already serious in Metro by excessive wear of rail profile, and excessive noise in sharp curve line. But effective scheme for the rail maintenance is established yet in our country. To work out such a problem by laboratory test or simulation, the wheel-rail contact simulator was developed. The simulator was developed to test various phenomena on wheel and rail surface by contact of wheel and rail at speed of maximum 400㎞/h using real scale wheel and rail which are also variable. And, using the simulator, it can be investigate deterioration phenomena of wheel and rail under various contact angle, attack angle, running speed, environmental condition, wheel and thrust load condition. The test results using the machine can be used for improvement of profile of wheel and rail, estimation of life period of rail and wheel etc, and, after all, it leads effective maintenance of wheel and rail.
