ABSTRACT

Values of penetration factor of wheel and rail surfaces that is used on application of fast algorithm for solution of normal contact problems are defined. Three cases had been considered: contact area has not strongly expressed spatial character; contact patch is situated nearby middle of rail rolling surface, radii of curvature of wheel and rail profiles have close values; contact patch is situated on fillet sections of the profiles.

KEYWORDS
