Analytical calculation of the coefficient of increasing the moment of resistance to milling the ground when the cutter hits the stump

Abstract

One of the main operations in peat soil processing is milling. The entire subsequent production process depends on the quality of the milling. The presence of wood inclusions in the soil greatly complicates the work. The sharply increased moment of loading that occurs when the cutter hits the stump is capable of removing both the transmission elements and the drive of the milling unit from the operational state. Therefore, at the design stage, it is necessary to take into account the dynamic loads arising from the meeting of the cutter with wood inclusions. Attempts to describe this fact were made earlier by various authors, but due to mathematical and methodological errors, they were not crowned with success. In this article, an attempt was made to "work on errors", which allowed one, taking into account all the previous errors and inaccuracies, to achieve the desired result.
