Abstract. Traveling of an automatic diagnostic machine along electrical transmission line is considered. Mathematical modeling based on Lagrangian mechanics of rigid and flexible bodies is carried out with the use of computer mathematics software. Saw tooth oscillations of the wires in the vertical plane and transversal movements of the type of a parametric resonance are revealed.  
Keywords: diagnostic of electrical transmission line, oscillation, Lagrangian mechanics, parametric resonance, mathematical software.
