Creation and experimental verification of a mathematical model of industrial debarking

Abstract

Abstract In the context of more intensive use of forest biomass, efforts to combat global climate change, the desire for more rational use of wood and an increase in surplus value in wood products, it can be assumed that primary woodworking processes require optimization. The aim of this work is the creation and experimental verification of a mathematical model of rational debarking of a log. The proposed mathematical model is based on a semi-empirical theory of fracture mechanics, the conclusions of which the authors optimize for the task of separating bark from wood during industrial debarking. During the experiments, a specially created installation was used. The results of experimental studies showed good quantitative and qualitative coincidences with the study results of the developed mathematical model. Thus, the developed model allows evaluating, at the stage of theoretical research, one of the main parameters of group debarking of timber. Namely, the time of timber processing taking into account the structural elements of the drum, parameters of pulpwood, their properties and temperature.
