  1. 1. Weight optimization of a harvesting head

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

    Författare :Anas Darwich; [2021]
    Nyckelord :Harvester; Forwarder; Topology optimization; Main plate; Skördare; Skrotare; Topologi optimering; Huvudplatta;

    Sammanfattning : With the development of the deforestation industry and the increased demand for sawn goods and woods over the world, created a need for more efficient harvesting methods, a need that was represented by mechanized harvesters and forwarders in forestry. These machines are efficient when it comes to mass production and can cut and delimb trees of all sizes and kinds. LÄS MER

  2. 2. 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

  3. 3. Modelling and Dynamic Simulation of Tracked Forwarder in Adams ATV Module

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Praveen Ramachandran; [2015]
    Nyckelord :racked Forwarder; Multi-body simulation; MSC. Adams ATV; Template Based Modelling; Bandskotare; Flerkroppssimulering; MSC Adams ATV; Mallbaserad modellering;

    Sammanfattning : Swedish forest industry is relying on the cut-to-length method for logging and there has always been a constant quest to make it more efficient and sustainable. Reduction of forest soil damage and operator vibration dosages are crucial steps that could facilitate meeting the above stated targets. LÄS MER

  4. 4. 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.

  5. 5. Model-based study of the energy efficiency of two different types of harvester cranes

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Johan Forsberg; [2014]
    Nyckelord :Forest machines; hydraulics; efficiency; Skogsmaskiner; hydraulik; effektivitet;

    Sammanfattning : In today’s forest industry two mechanized methods are used, the Tree Length (TL) method and the Cut To Length (CTL) method. With the Tree Length method, trees are harvested and extracted from the forest as a whole tree to be further processed whereas with the Cut To Length method trees are harvested, branches are removed and the tree is cut to desired length to be extracted by a forwarder.
