20.500.12556/RUL-114174 The effect of feedstock, knife wear and work station on the exposure to noise and vibrations in wood chipping operations Industrial chipping is becoming increasingly popular, as the result of a growing demand for woody biomass. Industrial chippers are large, powerful machines that generate much noise and vibration. This study explored some factors that may affect exposure to noise and vibration, namely: feedstock type (branches vs. logs), work station characteristics (truck cab vs. separate cab) and knife wear (new knives vs. blunt knives). Exposure to noise was significantly affected by all three factors, and it was higher for branch feedstock, separate cabs and blunt knives. The higher exposure levels recorded for the separate cab were especially insidious, because they were below and above the hearing threshold and would elude immediate perception. Exposure to whole-body vibration (WBV) was significantly higher for branch feedstock and for the separate cab. Knife wear seemed to determine an increase in WBV, but this effect had no statistical significance and the result could not be taken as conclusive. Among the three factors studied, work station characteristics had the strongest effect. Further studies may extend the comparison to a wider range of options, as well as explore the use of exposure variation for machine diagnostics. biomass fuelwood ergonomics safety biomasa lesna goriva sekalnik tresenje true false true Angleški jezik Slovenski jezik Članek v reviji 2020-02-19 12:38:32 2020-02-19 12:38:33 2025-04-22 15:22:33 0000-00-00 00:00:00 2018 0 0 14 str. no. 1, art. 7003 Vol. 52 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*83 2242-4075 10.14214/sf.7003 5071526 520811289 article7003_(1).pdf article7003_(1).pdf 1 D73ECABD6561E792D31A68D73E74CFC7 666dcada1c293ae1b7932a17f84c90507ecf0a539ef39739cb7938f7e3fc33d7 260735b1-146b-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201469 https://www.silvafennica.fi/article/7003 0 ded112e9-146a-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201468 Biotehniška fakulteta 0 0 0
