Summary
This paper deals with the method of calculation for tangential stresses over a non-elliptical contact patch, where it is possible to utilize with advantage the Kalker's simplified method FASTSIM. This method named FASTSTRIP is adapted for a non-elliptical contact area calculated by means of the strip method. The difference compared with the FASTSIM method is that the computation is executed along the strip separately, regardless of whether the size of a strip is smaller or longer than the virtual ellipse border. This method is almost rapid as FASTSIM and the results are similar to the CONTACT results. This method may be useful for rail vehicles for track dynamics computation.
