Vpliv tehničnih elementov verige motorne žage na obremenitve delavca s tresenjem : diplomsko delo - visokošolski strokovni študij - 1. stopnja = Impact of technical elements of chainsaw chain on exposure to vibration : B. Sc. Thesis - Professional study programmesŠvigelj, Žiga, gozdarNamen in cilj diplomske naloge je bil ugotoviti, kako različna priprava verige motorne žage, tip verige in drevesna vrsta vplivajo na obremenitve delavca s tresenjem, rok in dlani. Za ugotavljanje ... obremenitev delavca s tresenjem med prežagovanjem se je uporabilo prizmiran les jelke in bukve, ki se ga je predhodno prizmiralo s krožno tračno žago, na dimenzije 32 cm x 32 cm, napake lesa se je tekom poskusa izločilo. Za potrebo poskusa se je za prežagovanje uporabilo motorno žago Husqvarna 372 xp, na kateri je bila nameščena letev Stihl dolžine 45 cm, z 1,6 mm utorom ter verige proizvajalcev Stihl in Oregon, katere se je predhodno nabrusilo pod tremi različnimi koti ostrine rezilca in tremi različnimi globinami globinskih zob. Meritve se je opravljajo z merilnikom tresenja Pulse LAN Xi proizvajalca Brüel & Kjær, ki je bil povezan preko kabla z akcelerometrom, nameščenega na vodilnem ročaju motorne žage. Rezultati analize so pokazali, da je jakost tresenja ob neupoštevanju višine globinskih zob najmanjša pri kotih ostrine rezilca, kot jih priporoča proizvajalec verige. Ob upoštevanju višine globinskih zob pa jakost tresenja manjša pri nižjih globinskih zobih in manjših kotih ostrine rezilca, kot jih priporoča proizvajalec verige. Pri prežagovanju z verigami Oregon je jakost tresenja manjša kot z verigami Stihl ter manjša pri obdelavi jelke kot bukve. Ugotovitve raziskave so uporabne za zmanjšanje obremenitev rok in dlani profesionalnega gozdnega delavca in občasnega uporabnika motorne žage.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
