Design of the Scaled Adhesion Tester for Analyzing the Adhesion Characteristic of Railway Vehicles

초록

Railway vehicles driven by wheels obtain force required to propulsion and braking by adhesion force between wheels and rails, this adhesion force is determined by multiplying adhesion coefficient of the friction surface by the applied axle load. Scaled adhesion tester is an experimental device that contacts mutually with disc rollers which are equivalent to wheels and rails of railway vehicles, and rotates mutually by friction by driving each motor connected with roller axes. This paper describes the development of a scaled adhesion tester for analyzing of the adhesion coefficient between wheel and rail.
