eng	Experimental verification of stiffness characteristics of railway freight wagon buffers	Increasing length, weight and speed of freight trains lead to higher requirements on the running safety. The problem is related especially to braking of trains and their running through small-radius curves (including diverging parts of switches) where undesirable longitudinal dynamic effects can occur in the trainsets. From the point of view of the longitudinal train dynamics, a knowledge of stiffness characteristics of draw- and buffing gear of individual vehicles seems to be very important. Nowadays, the older types of friction-type suspension elements used in these components (conical belt springs, ring springs) are usually replaced by rubber-steel- or elastomer components with significantly different characteristics. Therefore, this work deals especially with requirements on the stiffness characteristics of railway freight buffers and their experimental verification in the context of their application into the multi-body simulations.	freight wagon; buffer; elastomer spring; stiffness characteristics; dynamic testing; measurement
