Method of calculation for dynamic strength of complex configuration frame structures of locomotives for transport engineering

Abstract

The article presents a numerical and analytical method for studying the bending-longitudinal vibrations of the load-bearing frame of the locomotive frame of a complex configuration in the form of an elastic rod of variable cross-section with variable mass, bending and longitudinal stiffness, based on methods: piecemeal linear approximation, iterations and the Boundary Element Technology. Numerical studies are performed in C # and in MATHCAD 15.
