Running Safety Test to Prove the Maximum Speed Performance of KTX-Sancheon

초록

In this paper, we describe the results of the evaluation of the running safety at the maximum operating speed as a test item of the KTX-Sancheon vehicle. In order to evaluate the safety when running at the highest speed, the measurement of the wheel load and lateral force, the derailment coefficient, and the reduction of the wheel load rate should be analyzed. We measured the interaction force between the wheel and rail for the high-speed vehicle and measured the safety of the vehicle. When the maximum operating speed is 331 km/h, the reduction rate in vertical wheel load, maximum lateral force per axle, and derailment coefficient are found to be safe when applying rules on railway safety standards.
