Sile na plug : magistrsko delo

Pajk, Luka

Med oranjem s traktorjem vlečemo plug in obračamo prst. Prst s silo deluje na plug in ga zavira, zato moramo s traktorjem delovati na plug z vsaj tolikšno silo, da se plug premika naprej. To silo ... imenujemo vlečna sila. S plugom v prsti ustvarimo napetost med delci prsti, ki se povečuje z večanjem sile. Ko povečujemo silo, dosežemo največjo napetost v prsti (mejo trdnosti) in povzročimo trajno deformacijo prsti. Na velikost vlečne sile vplivajo fizikalne lastnosti prsti, oblika orodja in način premikanja skozi prst. V magistrskem delu se posvečamo vplivu hitrosti na velikost vlečne sile. Za merjenje vlečne sile uporabljamo namensko narejen silomer. Merimo na 5 različnih parcelah z različno sestavo prsti in rezultate prikazujemo na grafu vlečne sile v odvisnosti od hitrosti. Izmerimo linearni odziv in iz prilagoditvenih premic za vsako parcelo izračunamo sorazmernostni koeficient med vlečno silo in hitrostjo. Najmanjše sile izmerimo v prsti s pretežno organsko strukturo, največje pa v prsti z velikim deležem ilovice.
