“…В работах [5][6][7] показано, что магнитное насыщение зоны контакта существенно зависит от распределения воздушного зазора между телами, следовательно, и от распределения кривизны поверхностей тел. Кривизна катков разного знака способствует улучшению условий намагничивания зоны трения, при этом повышается качество проводимого на двухкатковой установке эксперимента и достоверность получаемых данных.…”

The paper is dedicated to the circuit diagram substantiation of the specialized roller bench for researches of the magnetic field impact upon wheel adhesion with a rail. On the basis of the analysis of the experimental plants available at present for the study of the contact interaction of wheels with rails it is defined that two-roller benches are the most efficient for the investigation of different outer factors impact upon wheel adhesion with a rail. Taking into account mentioned above there is offered an original design of the two-roller bench equipped with the device for friction area magnetization. Two cylinders with parallel axes are theoretically a friction pair. Taking into account the presence of a non-concurrency arisen at roller manufacturing and mounting a point contact is realized in the bench. A bench formation is carried out according to a modular approach with the installation of rotary magnetic conductors. For the support of the largest magnetization of a friction area in longitudinal and transverse directions and for the decrease of stray flux in the bench there is realized a series connection of roller friction area with the sources of a magnetizing force. For the substantiation of rotary magnetic conductor position choice regarding a friction area of bench rollers there is carried out an analysis of magnetic field distribution in the friction area depending on the location of magnetic conductors. On the basis of the investigation results it is defined that a change of magnetic conductor position changes the orientation of a magnetic field vector, at that a roller friction area is magnetized in transverse and longitudinal directions. In view of this the bench design offered allows investigating the impact of longitudinal and cross magnetic fields upon friction in the contact of a wheel with a rail. Furthermore, it is defined that at small values of an angle between the direction of a magnetic field vector and the plane of a roller friction area a possibility to exclude the effect of roller magnetic additional loading appears.

The issues of filling the information model with data on the state of the wheel-rail tribosystem are considered. The “Program for modeling the transverse position of a wheelset in a track” is used, and the main modules of the program are described. The geometrical parameters of the contact of the wheel profile with the rail profile are obtained. The values of the nominal contact of the wheel with the rail for the extreme and intermediate positions of the wheel pair in the rail track are calculated. The displacement of the wheelset in the rail track, its slope, and the width of the contact of the wheel with the rail, the gap between the wheel crest and the inner face of the rail are determined. The obtained data are compared with the results of the experiment.
