Spreminjanje tehničnih parametrov traktorja pri vlačenju lesa - kriterij pri izbiri delovnega sredstva : doktorska disertacija = Changes in technical parameters of tractors in timber skidding - a criterion for selecting work equipment : dissertation thesisMarenče, JurijV nalogi sta predstavljeni metodologija in oblikovana merilna veriga za merjenje tehničnih parametrov traktorjev pri vlačenju lesa. Na kolesih traktorja so izmerjeni navori, obremenitev koles z maso, ... prevožena pot, na vrvi pa potrebna vlečna sila. Pri tem ugotavljamo, kako vplivajo nanje različni dejavniki, ki so zajeti v raziskavo.. Ti dejavniki so velikost in orientacija bremena, vzdolžni naklon vlake in smer vlačenja. Posebna pozornostje namenjena vlačenju navzgor, saj tedaj lahko presojamo zmožnost posameznih traktorjev pri delu v različnih terenskih razmerah. Z izbiro traktorjev je v raziskavi omogočena analiza vlačenja ob bistveno različnih dejavnikih, ki vplivajo na velikost tehničnih parametrov. Analiza izmerjenih tehničnih parametrov kaže na zmogljivost posameznega stroja. Na podlagi teh vrednosti in poznavanja konkretnih spravilnih razmer lahko presojamo in izbiramo tista delovna sredstva, ki lahko izpolnijo naše zahteve in pričakovanja.Type of material - dissertation ; adult, seriousPublication and manufacture - Ljubljana : [J.
