U ovom radu opisan je skider te njegove karakteristike. Pobliže su opisani dijelovi pogonskog sustava te vitlo za privlačenje trupaca, a zatim je objašnjen radni ciklus skidera. Nakon toga su detaljno opisani su uređaji za prikupljanje terenskih podataka ugrađeni na skider te je objašnjen postupak analize i obrade podataka. Obrađeni podaci dalje su korišteni u simulaciji konvencionalnog modela skidera koji je izrađen korištenjem programskog paketa MATLAB Simulink. Pomoću modela je procijenjen moment motora s unutarnjim izgaranjem koji se generira i prenosi preko transmisije na kotače. U nastavku je izrađen zamjenski model električnog skidera koji ima podjednake vozne karakteristike kao konvencionalni. Njegovom simulacijom dobivene su karakteristike baterije koja bi pokrivala potrebne zahtjeve za energijom pri radu skidera. Na koncu su izložene prednosti i nedostaci pojedinog pogona. This thesis describes skidder and its charasteristics. Parts of powertrain and winch used for pulling of logs were closely presented and thereafter the working cycle of a skidder was explained. After that, devices installed on the skidder for recoding of field data were described and data analysis and processing was explained. Filtered data was further on used in a simulation of a conventional motor drive which was made using MATLAB Simulink software package. Using computer model torque of combustion engine, which is generated and transfered to wheels by transmission, was approximated. Next, equivalent electric skidder model with similar driving characteristics as conventional was made. Through its simulation battery properties were defined. In the end, pros and cons of each drive were given. |
