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.
