    Analysis of Design of Passenger Cars Bogies for High speed Movement
    (The Silesian University of Technology, Poland, 2014) Kharchenko, Aleksandr V.
    EN: This paper gives an overview of the existing models of passenger cars bogies for high-speed movement, both Ukrainian production and production of other countries. As a result of this analysis it were determined the main tendencies to improve the design of running parts of passenger cars for high-speed movement. Also it was made a classification of bogies of passenger cars on different criteria.

    Usage of Quaternionic Matrices to Define Inertia Moments of Wheelset Taking Into Account Manufacturing and Assembly Errors
    (2011) Kharchenko, Aleksandr V.; Kravets, Tamila V.
    EN: It is given a computational algorithm of inertia matrix of wheelset that take into account manufacturing and assembly errors. An algorithm is based on quaternionic matrices. These matrices are made using Rodriguez-Hamilton parameters that take into account misalignments of symmetry axes and shifts of constructions in allowable limits.
