Mathematical modeling of reaction of lines of rails at climb-on of an unladen wheel

The problem on specific mathematical modeling of an unladen wheel of a wheel and axle set of a freight car is solved. These mathematical models make it possible to estimate a correctness of reaction values of lines of rails. It is recommended to use formulas received from the equilibrium condition of the moments of force relative to contact spots of wheels with lines of rails as final analytical formulas for calculation of unknown reactions of lines of rails.

To the estimation of the general intense-deformed condition of all-metal bodies of passenger cars

The variant of calculation of the intense-deformed condition of a body of the all-metal passenger car from action of loading is given. The idea of representation of a body as the three-layer girder is used, two bearing chords interacting through the central resilient layer. The latter has the properties characterizing resistance to the deflection, lengthwise displacement and turn of sections of bearing chords.
