Abstract
The aim of this work is to optimize the geometric form of additional plastic working elements of shock absorbers for various cases of impact loading. A finite-element model of a plastic element was used to evaluate the stressed state generated in cases of coupling of heavy freight trains with various types of mandrel. The results of numerical simulation show that application of a plastic working element with a convex generating line of mandrel is optimal for damping shock loads and minimizing damage during collisions.
