Mathematical Model of Oscillations of Bearing Body Frame of Emergency and Repair Railcars

Abstract: Summary. Nowadays, the importance of maintenance and effective use of available railcars in the railway transport is growing, and researchers and technical experts are working to address this issue with the use of various techniques. The authors address the use of analytical technique, which includes mathematical solutions for flexural and longitudinal fluctuations of the bearing framework of a railcar body frame. The calculation is performed in connection with the modernization of the body frame of emergency … Show more

“…For the electric locomotive VL-80s in the numerical calculation the value was taken as n = 8 , (and the error was δ =0,001). At justification of the dynamic model the following assumptions are accepted: the modernized main frame of the locomotive body is represented as an elastic rod (beam) with constant modulus of elasticity of the material E = const and density ρ = const, which has some static initial deflection radius R. The equations of bending-longitudinal vibrations for such a model are taken by analogy with the monographs [8,11].…”

“…This mechanical model allows us to describe the dynamic processes occurring in the system and calculate the dampener parameters taking into account the pre-set dynamic characteristics, which are important when calculating and designing new vibration dampeners for rolling stock, as well as when upgrading existing ones [4,18]. The resulting mathematical model also allows us to evaluate the influence of structural, power, mass parameters and track irregularities on the process of vibrations of the car body in the vertical and longitudinal horizontal planes, as well as the value of the dynamic load of the vibration dampener parts [19,20].…”
