THE METHOD OF ANALYSIS OF PARAMETRIC OSCILLATIONS AND RESONANCES OF THE CRANES ELEMENTS DURING THEIR START-UP PROCESSS. І

Abstract

Purpose. The method of analysis of parametric oscillations and resonances of the hoisting cranes elements during their start-up process is proposed . Methodology/approach. The mentioned above analysis is made with a help of two-mass model for the system “cargo-truck-rope” with a varied in time parameters. The methods of. Lagrange function and approach of L.D. Landau are used. Research limitations/implications. The deviation angle of rope from the vertical is small and calculation scheme for the analysis of parametric resonances in a system is such with a vibrations of the point of the suspension of horizontal and/or vertical type. Originali-ty/value. The main parameters of parametric resonances are determined.
