The object of the study is energy absorption devices (EAD), which are part of the passive safety system (PSS) of the new generation passenger railway vehicles. The research work purpose is the creation of a scientific base for the development of the passive protection system for passenger train vehicles and the train dynamics study taking into account the work of push-back automatic couplers, anti-climbers and PSS at emergency collisions with an obstacle on 1520 mm gauge railways. Methods of research are finite elements, linear algebra and numerical integration methods, as well as methods of experimental research. As a result of the research, the concept of passenger train passive protection at collisions on 1520 mm gauge railways has been developed. The algorithm, scientific and methodical support and mathematical models for the EAD constructions parameters choice have been developed. The reliability of the results of the mathematical simulation of the EAD prototype plastic deformation at impact has been confirmed by the data of its full-scale impact test. The developed EAD designs for new generation traction rolling stock and coaches, recommendations for passive protection of passenger train vehicles at collisions have practical significance. The results of research have been used by the Dnipropetrovsk National University of Railway Transport in the educational process when studying the passenger rolling stock development prospects. The sphere of use is railway transport. The socio-economic efficiency of the work consists of the fact that the construction of a high-speed passenger train with PSS will allow changing the national transport system. The importance of the research is the development of a modern scientific basis for solving applied problems related to improving the safety of railway transport by creating a PSS, the use of which will save lives of passengers and train crews, reduce the severity of consequences of an accident and reduce the costs of their elimination.
