Diplomsko delo zajema zasnovo stroja za sekanje in drobljenje lesa kot predpriprava medija za izdelavo lesnih peletov. Stroju smo izbrali ustrezen elektromotor in analizirali delovanje elektromotorja med zagonom. Določili smo pričakovane sile pri sekanju lesa z različnimi hitrostmi podajanja v sekač. Analizirali smo nihanje hitrosti in momentov med procesom sekanja. Nekatere strojne elemente smo na koncu še računsko preverili.

• Title: Development and analysis of the machine for cutting and crushing wood

Abstract

Thesis covers design of the wood cutting and crushing machine, used for pre-processing media for wood pellet production. We have selected appropriate electric motor and analysed the operation of the electric motor during start up. We determined expected forces for wood cutting with different feed rates in the cutter. We analysed the velocity and torque fluctuations during chipping process. On the end some of machine elements were additionally analytically checked.
