  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

    Sammanfattning : Denna rapport ar resultatet av ett kandidatexamensarbete som avlades på KTH under våren 2018 i maskinkonstruktion. Uppdragsgivare var KTH och Skogforsk; det svenska skogsbrukets forskningsinstitut, som är finansierat av skogsnäringen och den svenska staten. LÄS MER

  4. 3. Electrification of a diesel-hydraulic off-road machine

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Dhruv Phadke; [2017]
    Nyckelord :driveline control; efficiency; energy storage; XT28; drivlina; energilagring; reglering; XT28; verkningsgrad;

    Sammanfattning : This report is for the Master of Science thesis project undertaken for KTH Royal Institute of Technology in collaboration with the Forestry Research Institute of Sweden (Skogforsk) for the Forestry Master Thesis School. The aim of this project was to theoretically explore the possibility of replacing the hydraulic driveline with an electric series driveline and to understand the differences between using one or the other so that it can be convincingly concluded if a Diesel-electric driveline in Forestry forwarders is a worthwhile endeavour or not.

  5. 4. Energy analysis of a hybrid forwarder

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. 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
