Diminishing of dynamic loadings is in rope of drum oneend lift

Abstract

The analysis of literature sources on the study of oscillatory processes in ropes of lifts is
carried out. Previously, dynamic processes in ropes of hoists were considered without the use of
damping devices, that is, the rope's oscillations were damped due to its dissipative properties.
An equivalent torsion scheme of a single-end hoist is provided to determine dynamic loads in its
cableway, taking into account the dissipation of the rope and the damping device, which significantly
absorbs longitudinal oscillations, reduces the amplitude and damping time of the oscillations.
A mathematical description of the dynamic processes of the vibrational nature of a two-mass
system with a weightless rope is obtained in the form of an ordinary differential equation in
moments of elastic forces with constant coefficients. The results of solving the differential equation
are presented in the form of oscillograms. The region of rational parameters of the dissipative
coefficients of the damping device is determined, under which the rope dynamic coefficient
decreases significantly and tends to 1.
