Abstract

ǂV ǂskladu z zahtevami po posodobitvi odbojnih in vlečnih naprav na tirnih vozilih Slovenskih železnic so bili razviti vzmetni paketi z vzmetnimi elementi na podlagi vezave elastomer kovina. Pomemben del raziskav pri preskušanju vzmetnih paketov, po vgradnji v odbojne naprave železniških vozil, je naletno preskušanje vagonov. Z naletom obteženega vozila na mirujoče natovorjeno vozilo se ocenjuje zmožnost odbojne naprave in vzmetnega paketa, da obdrži pojemek mirujočega vozila v dopustnih mejah. V prispevku je predstavljen potek izvajanja preskusov z različnimi hitrostmi naleta in način določevanja koeficienta trka za razviti vzmetni paket. Rezultati opravljenih meritev kažejo, da največji pojemek med trkom obeh vozil tudi pri največjih hitrostih ne preseže dovoljene vrednosti po mednarodnih železniških predpisih.Prav tako so naletni preskusi pokazali, da razviti vzmetni paket poleg dušenja omogoča tudi počasno vračanje povratnega dela.

Secondary title: ǂThe ǂdevelopment and testing of rail-vehicle buffers filled with elastomer spring packages
Secondary abstract: ǂThe ǂdecision of the Slovenian Railway Company to modernise the shock absorbing and traction equipment of its existing rolling stock initiated the development of novel spring packages consisting of elastomer-metal-based elements. The crash testing of rail vehicles represents an important part of the testing of spring packages after their installation into buffers. The collision of a loaded rail vehicle with another loaded rail vehicle at a standstill is used to evaluate the capacity of buffers to retain the deceleration of the vehicle at standstill within the permissible limits. The results of tests at different collision velocities and the way of determining the collision coefficient for the developed spring package is described in this paper. The results of measurements show that the maximum deceleration during the collision of two rail vehicles does not exceed the permissible values defined in international railway regulations even at the highest velocities. Crash tests have also revealed that in addition to damping, the developed spring package enables slow reaction work.
