Development of passive safety elements presents very important activity directed in increase of safety in
railway traffic. Basic role of passive safety elements is to absorb requested amount of collision kinetic energy
through its own controlled deformation and to reduce the values of the force that is transferred to the rest parts of
the vehicle structure. In this way it prevents deformation of the middle-passenger zone of the wagon and at the
same time the number of human casualties and material damage is reduces to a minimum. Experimental
investigations of the several types of absorbers showed that the absorber which works on the principle of
shrinking the tube passing through special cone bush presents most acceptable solution from aspect of gradual
increase of deformation resistance, possibility of fully control of deformation process and the amount of energy
absorbed. Absorber developed in this paper consists of the seamless tube made by low carbon steel in quality
P235T...1 and the cone bush made by quench and tempered carbon steel in quality C45E. Quasi-static laboratory
investigations of elements of absorber and dynamic investigations realized through collision of passenger
coaches are the key part of experimental investigations and verification of prototype of absorber. Numerical
model of the tube absorber was developed. Nonlinear numerical simulations of deformation process using finite
elements method and strain rate dependent options were realized. Based on the results of experimental
investigations the key parameters which verifies developed numerical model for use in further researches in field
of quasi-static as well as dynamic environment (high deformation rate) were defined. During future
investigations, developed numerical model can be used in process of dimensioning of elements of different
absorption power, while for the final verification of prototype is necessary to perform dynamic test in accordance
to valid standards – CRASH TEST.
