A study on the analyzing the causes of corrugation of rail

초록

Corrugation occurred in some line of the Shinbundang line section. I measured the lateral force between the wheel and rail to analyze the cause of the corrugation of rail. This is different from the ground measurement method, which measures the wheel load and lateral force at specific points. This method is remarkable in that it can grasp the distribution of the lateral force and the wheel load of the total section. In this study, we measured the interaction force between the vehicle and the track and collected ground data to judge the appropriate cant and speed. As a result of lateral force analysis, it was predicted that the corrugation was due to the acceleration/deceleration for precisely adjusting the traveling speed of 90 km/h in the state of generating the geometrical wavelength of the Sin path when the wheel axis runs on the curved line.
