Dynamic effects in the rope of the double-end lift

Abstract

The analysis of literature sources on the study of dynamic processes in ropes of mine hoists
with a split drum and various landing gears is carried out.
Equivalent dynamic schemes of the lifting installation are given, taking into account the
application of the external torque to the drum and a mathematical description of the dynamic
processes of the oscillatory nature in the hoisting ropes.
A mathematical description of dynamical processes of oscillatory character in the ropes of a
double-end lifting installation is obtained for force transients in the form of an analytical differential
equation. The coefficients of the rope safety factor are determined taking into account dynamic
loads.
