О методике исследования процесса резания порубочных остатков дисковой рубительной машиной, оснащенной различными типами ножей

Abstract

Приводится методика исследования процесса резания порубочных остатков дисковой рубительной машиной, оснащенной различными типами ножей. При составлении методики исследований предусматривался общий подход к построению математических моделей процессов переработки древесины в щепу и для расчетов и оптимизации сил и моментов сил резания. При разработке методики процесс резания рассматривается как вращательное движение режущего элемента (ножа) заданной геометрической конфигурации с учетом сил сопротивления в рассматриваемой сплошной среде. В статье ставятся задачи для математического моделирования процесса резания древесины новой конструкцией ножа для оснащения рубительной машины дискового типа и сравнительного анализа его работы с традиционным ножом для рубки древесины. В результате расчетов должны быть получены математические модели, описывающие процессы резания порубочных остатков.

The methods for studying the process of cutting of forest residues disk chipper equipped with different types of knives. In drawing up the research methodology provides for a general approach to the construction of mathematical models of processed wood into wood chips and for the calculation and optimization of the forces and moments of the cutting forces. In developing the technique cutting process is regarded as rotational movement of the cutting element (blade) of a given geometric configuration to the resistance forces in the given continuous medium. The article raises the problem of mathematical modeling of wood cutting knife new design for equipping the chipper disc type and the comparative analysis of his work with a traditional knife for chopping wood. The calculations must be received by the mathematical model describing the process of cutting of forest residues.
