Item Choosing of Suspension Gear Parameters of Coache Model 61-779(Department of Railway Vehicles, Aircraft and Ships, BME Section of Rolling Stock, SSME, Budapest, Hungary, 2013) Myamlin, Serhiy V.; Prikhod'ko, Vladimir I.; Zhyzhko, Victoriia V.; Shkabrov, Oleg A.EN: Researches that focused on choosing of running gear's parameters and especially on spring suspension parameters are very important during creation of new passenger rolling stock. In the research calculations that determine strength characteristics of springs of central and axle-box suspension gear of bogies during its (bogies) using under coaches' (passenger cars) model 61-779 of JSC "Kryukov car-building company" are done and relevant dynamic parameters are determined. The simulation used a computer program «DYNRAIL», developed in Dnepropetrovsk National University of Railway Transport (DNURT). As a result of research parameters of spring suspension for designs of new passenger cars chosen.Item Investigation of Dynamic Characteristics of Gondola Cars on Perspective Bogies(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпропетровськ, 2014) Myamlin, Serhiy V.; Pysmennyi, Evhen O.; Bubnov, Valerii M.EN: Purpose. In this paper, it is necessary to examine the dynamic properties of the gondola car with bogies, model 18-1711 when it moves on straight and curved sections of a track. Methodology. The calculations were performed using the object-oriented programming on the program "Dynamics of Rail Vehicles" ("DYNRAIL" Myamlin S.V. registered 20.03.2003). Mathematical models of a gondola car and bogies 18-100 and 18-711 were created for the calculations. Findings. Dynamic performances comparison of the gondola car with bogies 18-1711 and the gondola car with bogies 18-100, obtained by calculation method was carried out. Originality. Firstly calculations in order to determine the dynamic properties of the gondola car with bogies 18-1711 when it moves on straight and curved sections of track were performed. At the same time an assessment of the dynamic characteristics of the gondola car was made. The following dynamic standards were determined: the coefficient of vertical dynamics (Cdv), the coefficient of horizontal dynamics (Cdh), and the safety factor against derailment (SFd). Track irregularities in vertical and horizontal transverse planes were assigned as perturbations. They should be so that the dynamic indexes of the widely used in operation gondola car on bogies model 18-100 keep in admissible range of speeds up to 80km / h for the empty gondola car and at speeds up to 90km / h for the loaded gondola cars. Practical value. As a result of the calculations and comparisons of their results, we have findings that the use of bogies with bilinear characteristic of the central suspension will improve the dynamic performances of gondola cars, currently operating on bogies, model 18-100. And by improving the dynamic performances it is possible to increase the permissible speeds of these cars motion.Item Study of the Dynamic of Interregional Dual-System Electric Train of JSC "Kryukov Car-Building Company"(Department of Railway Vehicles, Aircraft and Ships, BME Section of Rolling Stock, SSME, Budapest, Hungary, 2013) Myamlin, Serhiy V.; Prikhod'ko, Vladimir I.; Zhizhko, Viktoriya V.; Duzik, Vadym M.EN: The purpose of this study is a theoretical evaluation of dynamic parameters of the head and the intermediate dual-system electric interregional train of JSC "Kryukov car-building company" throughout the range of operating speeds. The simulation uses a computer program «DYNRAIL», developed in Dnepropetrovsk National University of Railway Transport (DNURT). A results of the theoretical studies of dynamic loading of the head and Intermediate cars of dual- system interregional electric train it's received a confirmation of design speed, which is 200 km/h.Item Моделювання динаміки спеціалізованих вантажних вагонів з урахуванням контргребеня(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпропетровськ, 2011) Мямлін, Сергій Віталійович; Мямлин, Сергей Витальевич; Myamlin, Serhiy V.; Дегтярьова, Л. М.UK: В статті запропоновано математичний опис взаємодії колеса спеціалізованого вантажного вагона і рейки, при цьому розглядається поверхня кочення колеса особливої конфігурації. З використанням варіанта колісної пари з контргребенем для немагістральних спеціалізованих вантажних вагонів запропоновано результати моделювання руху екіпажу.
