ON AN APPROACH TO THE EVALUATION OF THE STRENGTH OF A SPATIAL ROD SYSTEM UNDER IMPACT LOADING

DOI: 10.17804/2410-9908.2015.2.016-023

An estimation formula for determining the force of interaction between the mass of an electric locomotive and an obstacle is obtained. To determine its parameters, a mathematical model describing the intense strain state of the cabin of an electric locomotive at arrival on an obstacle, including cellular elements, is developed. The loading in the cabin elements is evaluated by the elastic-plastic and dynamic model of material resistance to deformation.

Keywords: thin-walled elements, strength, impact interaction
