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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

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

    Abstract : 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. READ MORE

  3. 2. Energy analysis of a hybrid forwarder

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Wenqi Wu; [2017]
    Keywords : active suspension; pendulum arm; Adams co-simulation; hydraulic simulation; energy consumption; Aktiv dämpning; pendelarm; Adams; samsimulering; hydraulisk simulering; energiförbrukning;

    Abstract : This report is the result of Master of Science thesis project developed for KTH Royal Institute of Technology in collaboration with the Forestry Research Institute of Sweden (Skogforsk) for the Forestry Master Thesis School 2016. In the past few years, Adams MBD models have been created to verify the better comfortability of six-wheeled pendulum-arm-suspension compared to bogie-suspended forwarder. READ MORE

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

    University essay from KTH/Maskinkonstruktion (Inst.)

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Maskinkonstruktion (Inst.)

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

    Abstract : 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.

  6. 5. Realization of a downscaled pendulum-arm suspended forwarder

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Petter Norder; Björn Sandegård; [2015]
    Keywords : Scale model; Skogforsk; Pendulum arm suspension; Skalmodell; Skogforsk; Pendelarmsdämpning;

    Abstract : Almost all logging in Sweden is carried out by the Cut-To-Length method. The method is carried out by two machines, a harvester and a forwarder. The forwarder transports the cut logs from the forest to a landing area for further transportation. READ MORE
