Analysis of the Wheelset and Turnout Crossing Interaction by Multibody and Finite Element Simulation

摘要

In this paper the interaction between the wheelset and railway turnout crossing is performed using a multi-body system dynamic simulation and a finite element simulation. The 1:15 turnout crossing which is based on the drawing from the manufacturer is used in the multi-body system model. The profiles of the wing rail and crossing are used as input into the finite element model to create threedimensional crossing geometry. In the finite element simulation the dynamic response of a whole wheelset while passing a crossing is obtained. By quantities such as wheelset displacements and contact forces in the rails, the dynamic responses of both models are compared and validated to ensure that with the reference conditions the results from both models are comparable. The collaboration provides more possibilities for further simulation of the wheel/crossing interaction such as variation of the initial conditions.
