  1. 1. Real time control of an active pendulum arm suspension system for a downscaled XT28 forwarder model

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Niclas Määttä; Adam Westermark; [2023]
    Nyckelord :mechatronics; offset-free MPC; MPC; LQR; XT28; forwarder; pendulum arm; forestry; mekatronik; offset-free MPC; MPC; LQR; XT28; skotare; pendelarm; skogsbruk;

    Sammanfattning : A forwarder named XT28 has been developed in joint collaboration between eXtractor AB, Skogforsk AB, KTH, Linköpings Unversity, Sveaskog, and Bosch Rexroth. The forwarder is equipped with six hydraulic active suspension pendulum arms. LÄS MER

  3. 2. Leveling controller for a forwarder with pendulum arms

    Master-uppsats, KTH/Mekatronik

    Författare :Tianrui Liu; [2022]
    Nyckelord :;

    Sammanfattning : See file .... LÄS MER

  4. 3. Control Strategy Investigation for a Down-Scaled Forwarder : Refinement, Testing and Analysis

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :ANQING DUAN; [2017]
    Nyckelord :;

    Sammanfattning : The predominant method of trees harvesting in Nordic countries is cut-to-length logging (CTL). CTL is realized by two machines: a harvester which is used for felling the trees, and a forwarder which is used for transporting the logs to a road accessible by trucks. LÄS MER

  5. 4. Test and refinement of a down-scaled actively suspended forwarder

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Qingxiao An; [2016]
    Nyckelord :Scaled vehicle; pendulum arm suspension; rough ground test; Nedskalat fordon; pendelarmsfjädring; ojämn mark; provning;

    Sammanfattning : Cut-To-Length (CTL) logging is the dominating logging method in many parts of the world. CTL logging requires a forwarder for the logs from the felling area to a landing area. Due to the harsh off-road working conditions, a well performed suspension system is necessary for the forwarder. LÄS MER

  7. 5. Heterogeneous MBS forwarder modeling and co-simulation

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Liunan Yang; [2015]
    Nyckelord :Co-simulation; ADAMS; MATLAB Simulink; Forwarder; Active suspension; Pendulum arm; ADAMS; MATLAB Simulink; Skotare; Aktiv fjädring; Pendelarmar;

    Sammanfattning : The forwarder acts as an important role in mechanized Cut-to-Length timber harvesting system. But the majority of forwarder products on the market are not suspended or simply suspended by bogies which limit the riding quality of forwarder and result in soil damage due to large tireground interaction force.
