Digital simulation of forest multioperation machine operation

Abstract

In this article, an innovating multi-operational forest machine (MOFM) is proposed. MOFM is based on the tractor processor (TP) and it is planned for bucking trees and making bundles from waste wood. The article presents the results of digital simulation experiments with MOFM compared with TP. The article gives the results of modelling of forests with a reserve of 150 m3/ha and with an average volume of tree trunk volume 0.40 M 3. In the article, the length of the winch rope is assumed from 10 to 30 m. Experiments were performed for different technology options. When working in parallel operations of the MOFM and winch, productivity increases with increasing skidding distance. Productivity increases until the skidding cycle time is less than the MOFM cycle time. After that, MOFM productivity decreases. For our case, the optimal skidding distance is close to 25 m. The length of the queue of trees to MOFM is increased as the skidding distance increases. The queue length stops growing when the skidding distance is 25-30 m. Digital simulation models were realized as computer programs. These models allow you to choose rational MOFM parameters for different forest characteristics.
