Моделювання режимів роботи електроприводів підйомних лебідок вантажопідйомних машин

Abstract

The general characteristics of load-lifting machines and kinematic schemes of their lifting winches are carried out. Load-lifting machines with unbalanced, balanced and partially balanced kinematic schemes of lifting winches have become the most widespread. In general, their mathematical models are presented and the corresponding structures, which are implemented in the Matlab environment in the form of elements of the library Simulink, are proposed. The simulation of operating modes of automated electric drives of lifting winches with different kinematic schemes in the case of the use of frequency-regulated electric drive is carried out.
