Abstract
The problem of formalization of the elastic line of thin steel strip greater flexibility occurred during research elastic elements with non-linear characteristics for use in various types of damping devices suspension vehicles. Such rods have great elastic displacement when operating within the elastic material, in particular when the axial loading in the supercritical region where the axial load exceeds the Euler force. The method of elliptic parameters used for the analysis has shown not only high correlation with experimental data, but also preference in the course of formalization of deformation of the elastic line.
Keywords: elastic line; thin strip; greater flexibility; formalization; axial loading.
