The paper presents a simulation method for testing the energy absorbed by the absorption sys-tems of rail vehicles equipped with a soft absorber. The method makes it possible to verify the actual behaviour of the absorption system during an impact of two vehicles. The first part of the paper describes the structural elements of a railway vehicle performing the function of an energy absorber during an impact according to the EN 15227 standard. A soft absorber, the so-called honeycomb, is analysed in detail. It is a multi-cellular structure often used in rail vehicles due to its properties of controlled deformation. The literature study describes the research conducted on this element. The analytical part describes a general mathematical model of a rail vehicle colli-sion according to Scenario 1, in which the collided vehicles are of the same type, and Scenario 2 for vehicles of different types. A computational impact simulation for the two scenarios has been carried out using the specialist software Mathcad, and the results are presented in graphs. The paper end with conclusions presenting the application possibilities of the tool which has been developed.
