Удосконалення існуючого математичного забезпечення Head Ushkalov Victor F., Registration Date 26-04-2007 Organization Institute of Technical Mechanics of the National Academy of Sciences and National Space Agency of Ukraine popup.description2 The analysis of the literature is carried out and the line of investigation on change of the form of a wheel disk and profiles of contact pair "wheel - rail" for railways of Ukraine and other CIS countries and Baltic (track gauge of 1520 mm) is chosen. Mathematical model of spatial vibrations of a four-axle freight car moving along the track of arbitrary shape in plan is improved by taking into account wheel disk elasticity. The influence of the use of wheels with conformal interaction with a rail on the wheel-rail deflected mote is estimated under the freight car motion along straight and curvilinear track segments. Wheels with the profile proposed by ITM are investigated after the different travel run. Product Description popup.authors popup.nrat_date 2020-04-02 Close
