Design of load profile for running performance verification of railway vehicles to the running on small curve

초록

Derailment is a key element of running safety. A method for evaluating the risk of derailment of the commonly used theory is the theory of Nadal. According to the theory, a limit value of derailment coefficient is dependent to friction coefficient between wheel and rail. In fact, the friction coefficient of the running vehicle is varies every moment. Therefore, it is impossible to directly measure the friction coefficient. Instead, many countries around the world make the measuring wheel-set for evaluation the running safety. However, evaluation of running safety through a field test is required a lot of time and cost. Therefore, the simulation test in the laboratory to be an alternative. I am predicted the wheel load and lateral force on the track of curve radius 120m. In this paper, the actual rotation tester was designed to be applied to the load profile. As the study were calculated load and speed conditions according to the type of track and vehicle. We have DB are expected to contribute the development of a railway vehicle dynamics.
