Investigation of technological variants of performing processing operations of logging works using chainsaws

Abstract

Abstract The paper proposes a new method to evaluate technical, technological and organizational parameters of the developed automated system for designing logging operations based on multi-level structural improvement in the processing procedure. To justify the optimal technology of this procedure, the complex indicator of specific energy consumption was introduced, and a mathematical apparatus sensitive to changes in a wide range of the worker’s characteristics was developed. Besides, the natural environment of the parameters of gasoline-powered tools, technology and process organization, and the worker’s individual characteristics such as qualification and fatigue were considered. The algorithms and programming software written in Delphi were elaborated to reliably predict the operation of various sets of gasoline-powered tools in 12 possible technological sequences based on the mathematical apparatus obtained. The discrepancy between the experimental and modeling data was found not to exceed 3-6 %. As a result of using the considered tools and software, it became possible to improve the performance of processing operations by identifying optimal technical and technological solutions under the given conditions of production and the natural environment at the stage of technological design.
