INFLUENCE OF ELASTIC AND INERTIAL PARAMETERS OF THE PULLEY OF VARIABLE MOMENT OF INERTIA ON ITS DYNAMIC CHARACTERISTICS

Abstract

In order to reduce the dangerous effects of resonant phenomena that occur during the start of the ropeway drive, this paper proposes the use of a pulley of variable moment of inertia. The influence of elastic and inertial parameters of the pulley on the values of eigenfrequencies was investigated using simulation modeling in the Solidworks computer-aided design system with Motion application. As a result, it was found that a decrease in the mass of the load with a proportional increase in stiffness and dissipation coefficient of the spring blocks leads to a decrease in the eigenfrequency of the pulley; reducing the stiffness of the spring blocks under conditions of constant weight of the load causes a significant reduction in the eigenfrequency of the pulley, but requires the use of load limiters; increasing the share of the mass of the load in the total mass of the pulley leads to an expansion of the range of changes in the moment of inertia of the pulley.
