Two-axle bogie vibration damping system with additional damping elements

There are no optimal vibration damping designs for safe movement at the present stage of the development of high-speed rail transport. The purpose of improving existing structures is their ability to simultaneously dampen both longitudinal and transverse vibrations. For dynamic research, an analytical method has been developed for calculating the stresses and deformations of the sidewall of the frame of an electric locomotive bogie in motion, taking into account the unevenness of the joints. The result of the work on creating a new design of a two-axle bogie of a railway vehicle, with additional damping elements of the vibration damping system, is the Patent of the Republic of Uzbekistan for the invention No. IAP 06498 [1]. The considered design is universal and suitable for a subway car, motor locomotive, or railcar.
