  3. 17. Modelling and improvement of 2-Speed Smoothing System

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Oskar Nilsson; [2021]
    Keywords : Simulink; Skid-steer; Hydraulics;

    Abstract : A skid steer loader is a machine used in construction for multiple tasks. Its small size and versatility makesit a use-full addition to any work site. The machine is driven by a combustion engine that in turn powers ahydraulic pump. This hydraulic fluid from the pump is then directed to either motor to propel the vehicle. READ MORE
