- 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.
