DESIGN OF AN ELEMENT USED TO ABSORB THE IMPACT ENERGY FOR A RAILWAY TRANSPORT VEHICLE

Abstract

The main objective of the paper is dimensioning of the impact energy absorption elements and verification of their mechanical strength in the case of a rail transport vehicle. The calculation consisted in optimal setting of the inside diameter, wall thickness and cylinder height. In the calculations, the standard for cold drawn pipes EN 10216: 2002 has been taken into account so that the chosen dimensions correspond to those delivered by the industrial suppliers. Based on the calculations presented in the paper, a numerical model will be developed, analyzed using the finite element method and validated experimentally.
