Modelling of the Rubber-metal Suspension Components in the Railway Vehicle Dynamics Simulations


Abstract:
The paper features several one-dimensional models to represent the rubber springs used in the dynamics simulations for the railway vehicles. Similarly, it includes a description of a model for the illustration of the mechanical behaviour of a mix coil spring - rubber employed in the secondary suspension of the passenger cars. The principle of this model relies on the overlapping of three components - elastic, viscous and the dry friction. The dependence of the force developed in the mix coil spring - rubber on the frequency and amplitude of a harmonic excitation is highlighted via the numerical simulations.


Keywords:
suspension; railway vehicle; rubber models; coil spring - rubber; friction
