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. Topology optimization of a swing arm for a track driven vechile

   University essay from Umeå universitet/Institutionen för fysik

   Author : Philip Nilsson; [2018]
   Keywords : topology optimization; optimization; structural analysis; ANSYS; structural simulations; topologioptimering; optimering; hållfasthetsanalys; ANSYS; hållfasthetssimuleringar;

   Abstract : The development in additive manufacturing methods has cleared the path for topology optimizationby making it possible to produce complex geometries, which would not be possible to produce bytraditional manufacturing methods. Topology optimization uses iterative structural computations tond an optimal material distribution given a maximum optimization domain, load cases and/or otherstructural criteria. 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. 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. Multi-objective optimization and performance evaluation of active, semi-active and passive suspensions for forestry machines

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Federico Baez; [2014]
   Keywords : Forestry machine; suspension; multi-objective optimization; forwarder; pendulum arm; active; semi-active; passive; XT28; Multibody Dynamics; soil-friendly; off-road; Skogsmaskin; fjädring; optimering; skotare; pendelarm; aktiv; semi-aktiv; passiv; XT28; flerkroppsdynamik; markvänlig; off-road;

   Abstract : The development of forestry machines is currently heading towards new solutions that reduce their impact on the environment and in particular on the soft forest soil in which the machines operate. The terrain conditions that forestry machines encounter in their regular duties can be very rough, and if the vehicle-ground interaction is not properly controlled cumulative damage can progressively aggravate these conditions and potentially render a route or a zone impracticable, apart from causing a detrimental effect in the forest environment.
