  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. Control Method for an Automated Forest Machine Based on Deep Reinforcement Learning

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

    Author : Youchen Sun; [2023]
    Keywords : ;

    Abstract : An automated forest machine was designed in order to improve the working environment of today’s forest machine operators. In order to realize the autonomous control of the forest machine, model-based methods such as A* and dynamic window were used in previous projects. READ MORE

  4. 3. 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

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

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

    Author : ANQING DUAN; [2017]
    Keywords : ;

    Abstract : 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. READ MORE

  6. 5. 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
