The intelligent mechatronic system for open pit mining to increase the operation life of equipment

This article proposes the intelligent mechatronic system that is based on the controlled induction motor drives. This system is effective to increase the technical operation life of mining machines for open pit mining. It allows control of the dynamic state of the mining machine mechanical components, thus the dynamic loads in the transmission are reduced and the accumulated intensity of fatigue wear becomes smaller. In the beginning, the article describes the concept of such system. The central parts demonstrate the control algorithms of the spring forces in the transmission and observe the estimation of immeasurable mechanical values needed for the mechatronic system operation. In the end of the article, the authors confirm the effectiveness of the proposed solutions experimentally using the data from the acting electric rope shovels
