Original Abstract

The article describes some methods used in modeling and simulation of a drive of electric-hydraulic excavator. The paper introduces basic model schemes of the drive system, the simulation models of the electric motor system, of the pump driven by the electric motor, examples of simulation results – time courses of model quantities received either by means of Matlab/Simulink or a set of differential equations. The electric drive powered by electric accumulators as a single source of energy is a crucial innovation in contradiction to the traditional drive of excavator by an internal combustion engine. In our case, we have innovated the mini-excavator E19 up to 2 tons produced by the company Bobcat Doosan.
