The bucket wheel excavator (BWE) is a machine with continuous operation which cuts the rock with the help of the buckets installed on the rotor, performing at the same time the transfer of the excavated material to the main conveyor, with the help of the conveyor belts installed on its boom. The operating equipment is the rotor (bucket wheel) which performs a rotation movement in vertical plane and, with the help of the boom, a horizontal pivoting movement and a vertical ascendant – descendent movement. In this paper we present a modality of determining the operation power of an excavator rotor using numerical methods. The aim of approaching some virtual models which allow the analysis of the operation of some components of the rotor excavator resides in the improvement of the cutting – loading system, the reduction of the specific energy consumption during the cutting operations while maintaining the installed power for the operation of the rotor and the increase in the excavation capacity, respectively the degree of intensive use of the excavator.

A numerical method for the calculus of the operation power of the rotor of a bucket wheel excavator
