    Abstract
  • According to the coupling relation of wheel rail contact, a direct method is proposed to evaluate wheel derailment based on the wheel rail contact point.The advantage and the principle of the method are described. As an example, wheel derailment was simulated for a full scale freight car negotiating a curve from the point of view of vehicle track coupling dynamics.The results show that this principle is a very good method to evaluate vehicle derailment especially in simulation of railway vehicle dynamics.
