축소 차륜 및 레일륜을 이용한 점착계수 시험

초록

Even though adhesion is the most important factor that determines the velocity limit and braking performance of train, there is no standard and no test result for adhesion test in Korea. So we tried to perform the adhesion test for the small-scale wheel and rail rig using High Speed Wheel-Rail Contact Simulator in KRRI. The absence of standard made us perform the test in various ways and check the appropriateness of the test methods. So performed was the test of the small-scale specimen under the dry/wet conditions, or under the condition of varying rotation speed, and the comparison of results with other references.
