“…An analysis of studies of transient modes of train movement showed [1] that the coupling of freight cars with long loads, inter-car connections and bogies is a dynamic system with many degrees of freedom. When testing for impact, the coupler performs complex spatial vibrations due to the work of draft gears and spring suspension of the car, as well as the turnstile support and fastening device [2].…”

The article analyzes the motion of a wheelset along a path of unequal length with shaft wear of the rails. The authors have studied the influence of an external disturbing force on the parametric system “wheel-rail”. The considered problem is solved on the basis of a mathematical model of interaction of a pair of wheels and an unequal rail, taking into account the additive effect of unequal stiffness on a rail vehicle. It is shown that taking into account the unequal elasticity of the track in the longitudinal direction allows to determine more precisely the resonance regions and to evaluate the decrease or increase of the acceleration level and the amplitudes of the impact of the unsprung mass of the rail vehicle.

“…All measurements were classified by speed. In each run, one maximum amplitude value of the dynamic process was selected [11]. Side forces, the ratio of frame forces static load from the wheelset rails, the stability criterion of the rail grate from shear, the coefficients of stability margin against the derailment of the wheel and the smoothness of ride were taken as evaluation parameters [12].…”

This article aims to study experimentally the dynamic properties and traffic safety actions for gondola cars with bogies with diagonal links, operated on the territory of the Republic of Kazakhstan. The main results obtained during tests of gondola cars on bogie with diagonal links when they move along straight and curved sections as well as on switches are presented. The estimation of: dynamics coefficients, stability margin coefficients against derailment, lateral forces transmitted from the wheel to the rail, ratio of frame forces to a static load from the wheelset on the rails, and accelerations are made. The paper analyses the simulation of a polymer layer of rubber vibration absorber, to be installed between the rubbing surfaces, such as the link side of frame axle unit, and host unit is open-bearing, with lateral support of the three-piece freight car bogies, operating on the territory of the Commonwealth of Independent States. The model developed in this article consists of a rheological model of a Maxwell cell, a Fancher spring and an element which has the function of non-linearity. The simulation model can be used to study the characteristics of vibration dampers, gaskets and other power elements that have polymer properties and are installed at other types of transport and not only.
