dc.description.abstract | Tendencies to increase the speed in the railway transport lead to intensive work on
active and passive safety improvement of railway vehicles with the aim to reduce possibilities of
collision to a minimum. Frequently, we have collisions in the main railway stations during shunting
and forming trains at speed higher than allowed. Consequences of these collisions are damages of
the vehicles structure and sometimes parts of infrastructure that require time for repairs. These
reduce the availability of the vehicles and causes loss of profit and increase of maintenance costs.
Subject of this paper is experimental investigation of absorption characteristics of foam filled tube
collision energy absorber which works on the principle of shrinking the seamless tube through
special cone bushing. This type of absorber is intended for mounting in a line with standard buffer.
Tube is filled with high density polyurethane foam with the aim to increase deformation resistance
during collision. Using shrinking process energy absorption occurs by elastic-plastic deformations
of the tube, friction between the tube and the cone bushing and compression resistance of high
density polyurethane foam. This type of absorber gives gradually increase of the deformation
resistance and higher absorption power in comparison with empty seamless tube. Experimental
researches were realized on the hydraulic testing machine in the laboratory conditions. During
tests, reaction force on defined stroke was measured. Results of the experimental investigations of
foam filled tube collision energy absorber and empty tube collision energy absorbers were
compared. | sr |
