20.500.12556/DKUM-60740 Razvoj hibridnega stroja za delo na strmem terenu Development of a hybrid machine for working on sloping terrain Obravnavamo problem vzdolžne obdelave nasadov na strmih kmetijskih površinah, ki se danes obdelujejo z vitelnimi obdelovalnimi stroji. Za ugotavljanje energijske učinkovitosti obdelave kmetijskih površin smo uvedli pojem izkoristek procesa obdelave kmetijskih površin, s katerim je opredeljeno razmerje med energijo delovnih priključkov in skupno vloženo energijo. Razvili smo koncept stroja, ki izkorišča razpoložljivo potencialno energijo in v času vožnje po strmi površini navzdol uporablja dva delovna priključka hkrati . Izdelali smo samovozni stroj z vitelnim in kolesnim pogonskim sklopom ter s hidrostatičnim prenosom moči. Prednosti novega stroja smo dokazali z metodo nevronskih mrež. Napisali smo algoritem za ugotavljanje in napovedovanje izkoristka procesa obdelave strme kmetijske površine. Rezultati izboljšav so manjša poraba goriva, manjša količina proizvedenega CO2 in manjši stroški obdelave. The thesis deals with the problem of longitudinal land cultivation on sloping agricultural land, which is currently being cultivated using agricultural winch machinery. In order to establish the energy efficiency of land cultivation, we introduced the term cultivation efficiency of agricultural land, which defines the ratio between the energy of machinery attachments and the total input energy. We developed the concept of a machine that utilises the available potential energy and uses two machinery attachments simultaneously when the machine drives down the slope. We made a self-propelled machine with a winch-supported drive transmission and a wheel drivetrain and hydrostatic power transmission. The advantages of the new machine have been proven using the neural network method. We wrote an algorithm for establishing and forecasting the cultivation efficiency of sloping agricultural land. The improvements resulted in lower fuel consumption, lower CO2 emissions, and lower costs of cultivation. strma kmetijska površina potencialna energija izkoristek procesa obdelave vitelni stroj hibridni pogon nevronske mreže metoda matrik sloping agricultural land potential energy cultivation efficiency winch machine hybrid propulsion neural networks matrix method true true false [M.
