Obremenitev strojnika stroja za sečnjo z ropotom in tresenjem v razmerah Visokega krasa : magistrsko delo - (magistrski študij - 2. stopnja) = Exposure of harvester operator to whole-body vibration and noise under conditions of High karst : M. Sc. Thesis - (Master study programmes)
Meznarčič, Primož
Namen magistrskega dela je bil ugotoviti stopnjo obremenitev strojnika stroja za sečnjo z ropotom in tresenjem celega telesa pri delu na območju Visokega krasa. Tridnevna raziskava je bila izvedena ...na petih različnih strojih (John Deere 1470D in 1470E, Caterpillar 580 in 580C ter Valmet 941.1), petih lokacijah in na šestih strojnikih. Rezultati so pokazali, da je bila obremenitev strojnika z ropotom (LAeq.kor.) v delovnem času med 70,8 in 74,5 dB(A) oz. med 98,1 in 132,5 dB(C) glede na konično jakost ropota (LCpeak). Nobena od obremenitev z ropotom ne presega spodnje opozorilne vrednosti dnevne izpostavljenosti. Obremenitve s tresenjem so bile najvišje v aksialni (Y) smeri in glede na kazalnik RMS med 0,33 in 0,46 m/s2 oz. med 8,21 in 11,89 m/s1,75 glede na kazalnik VDV. Obremenitve s tresenjem na dveh deloviščih presegajo opozorilne vrednosti določene z zakonodajo. V obremenitvah z ropotom med operacijami delovnega časa ni značilnih razlik, medtem ko so obremenitve s tresenjem značilno večje pri premikih stroja kot ostalih delovnih operacijah.
