Subject of research: vertical and horizontal dynamic loads on the rail track from the rolling stock. Regulations related to the direction of crews by rails when fitting into curved sections of track. Constructive methods to improve the characteristics of rolling stock in terms of force and friction load on the track. The purpose of the study: to create a scientific basis for the development, design and modernization of running gear of locomotives and wagons with improved traffic safety characteristics and reduced impact on the track. Scientific value of applied research: • scientific approach to the assessment of the dynamic qualities of rolling stock based on the criterion of degradation impact on the rail track; • regularities of degradation processes in the rail track in the operation of traditional rolling stock with normative and excessive deviations of the technical condition; • the impact of deviations of the geometric parameters of the crew of the rolling stock on the level of horizontal forces of the crews of the rail track; • model of interaction between the crew and the track, built on the basis of the transfer of contact loads between the contacts of the wheel pairs with the elements of the turnout; • new elements of the theory of fitting rail crews in the curve based on the clarification of the classical provisions of the dynamics of frictional interaction of locomotives and cars with the track. Developed: • technical solutions for the design of the device for a comprehensive assessment of comfort; • recommendations on certification of freight rolling stock according to the level of degradation impact on the track to obtain a permit for operation in mixed traffic on highways; • method of assessing the comfort conditions of high-speed trains on the basis of the criterion of smoothness; • experimental bench installation for research of freight car trolley elements Product Description popup.authors Bulich Dmytro M.
