Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Based on Hertzian contact theory, the distribution of the wheel-rail´s normal contact force in the contact area and the normal displacements of both contact bodies are calculated with the iteration algorithm. By defining different Kalker´s coefficients in every contact area respectively, one improved FastSim algorithm is introduced to calculate the longitudinal, lateral creep forces and spin moment, which there is multi-point contact happening between the wheel and rail. The calculation results are compared with the classical FastSim algorithm and Shen-Hedrick-Elkins theory, and the small differences between them as well as the considering of calculating creep forces in different discrete contact area means that the improved FastSim algorithm can get the better solution for the calculation of wheel-rail contact forces with multi-point contact.
