BUFFER TESTING IN ORDER TO EVALUATE THE LONGITUDINAL FORCES THROUGH COLLISION OF TWO RAILWAY VEHICLES

Dan-Mihail COSTESCU, Camil Ion CRĂCIUN

Abstract


The paper presents the issue of performing dynamic tests on the absorption capacity of longitudinal shocks that occur during the collision of two railway vehicles and their transmission to the elements that build-up the resistance structure of railway vehicles. The impact between the railway vehicles is normally achieved in triage, at train formation, but especially during braking, due to the pneumatic system, and performing collision tests can help validate the results obtained through simulation programs. The tests were carried out within the Railway Testing Center from Făurei - Romania, monitoring the value of the maximum force transmitted to the resistance structure, the maximum compression of the buffers and the determination of the maximum acceleration at impact.
