Vpliv napak lesa na produktivnost dela pri izdelavi prostorninskega lesa listavcev s cepilnim strojem Kolenc in krožno žago Krpan : diplomsko delo - visokošolski strokovni študij - 1. stopnja = The influence of wood characteristics onto production of firewood using Kolenc woodsplitter and circular saw Krpan : B. Sc. Thesis - Professional Study ProgrammesOvsenek, AnžeNamen diplomske naloge je bil ugotoviti ali premer in napake lesa vplivajo na učinkovitost proizvodnje in porabo goriva. Meritve za izdelavo diplomskega dela so potekale na zasebni posesti na Brezjah ... pri Tržiču. Ugotovljen je bil vpliv grč in premera bukovih sortimentov na produktivnost ter porabo goriva pri proizvodnji drv. Na podlagi popisa napak lesa so bili sortimenti razvrščeni v skupine. Pet sortimentov je imelo premere približno 50 cm, petnajst sortimentov pa približno 20 cm. Z ustreznim standardom so bili sortimenti razvrščeni v kakovostne razrede. Izmerjena je bila poraba goriva pri traktorjih in motorni žagi. Narejena je bila časovna študija proizvodnje drv in kalkulacija stroškov uporabljenih strojev. S statističnimi metodami je bila dokazana različna učinkovitost proizvodnje med tanjšimi in debelejšimi sortimenti. Pri operaciji cepljenje je bila učinkovitost proizvodnje tanjših sortimentov za 1 m3/h višja za kot pri debelejših sortimentih. Pri prežagovanju debelejših sortimentov z motorno žago je bila učinkovitost višja za 7,8 m3/h v primerjavi z tanjšimi. Grče prav tako vplivajo na učinkovitost proizvodnje drv. Učinkovitost proizvodnje pri sortimentih z grčami nad 40mm je bila na ravni cikla nižja za 0,27 m3/h in pri operaciji cepljenje za 1,41 m3/h v primerjavi z sortimenti brez grč. Povprečna poraba goriva motorne žage je znašala 104 ml/m3, maziva pa 23 ml/m3. Pri tanjših sortimentih je bila ugotovljena višja poraba goriva po enoti proizvoda (za 33 ml/m3), pri sortimentih z grčami pa za 40 ml/m3. Cena dela je v povprečju znašala 17,99 E/m3, pri drobnejših sortimentih 15,59 E/m3, pri debelejših pa 18,91 E/m3.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
