ABOUT SOME OF THE OSCILLATIONS IN THE MECHANISM OF THE PLANETARY TYPE

Abstract

The article deals with the problem of determining stable and unstable equilibrium positions of the mechanical system of planetary mechanism type with one degree of freedom. The mechanism oscillates in a vertical plane. The function of the potential energy of the mechanism is studied. The features of free nonlinear oscillations of the mechanism are also investigated by the phase plane method. Built phase portraits. The mathematical model of the mechanical system, described by a system of nonlinear differential equations, allows to detect and investigate such moments in the behavior of the system, which are not available in linear theory. The analysis of the dependence of the number of equilibrium positions on changes in the values of some parameters of the system. It is shown that the considered mechanism, depending on its geometric characteristics, can have one or more stable equilibrium positions.
