  1. 6. Influence of logging residues on MeHg accumulation in soil

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Axel Blomgren; [2018]
    Keywords : Mercury methylation; Forestry; Dissolved organic matter; Soil temperature; Soil water content;

    Abstract : Forestry has been found to increase the accumulation of methyl mercury (MeHg), a highly neurotoxic compound, in forest soils. However, little is known about how forestry influences catchment processes that governs the mercury (Hg) methylation process. READ MORE

  3. 7. Implementering av markfuktighetskartor : maskinförares upplevelser av information, utbildning och användande av markfuktighetskartan

    University essay from SLU/Dept. of Forest Resource Management

    Author : Louise Åkerstedt; [2017]
    Keywords : drivningsplanering; planeringshjälpmedel; markskador; förändring; motstånd;

    Abstract : Ett nytt verktyg som tagits fram för att förenkla drivning och drivningsplanering är markfuktighetskartor. Med hjälp av dessa kan blöta eller fuktiga partier i terrängen identifieras och därmed förenkla placering av exempelvis basvägar eller naturhänsyn. READ MORE

  4. 8. 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.

  5. 9. 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

  6. 10. Development of an active suspension control strategy for a forestry machine with pendulum arms

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Jorge Aguilar; Morgan Viktorsson; [2014]
    Keywords : ;

    Abstract : The forest industry depends on the cut to lenght method for production. The forwarder is one of the machines used in this process. These machines currently have no suspension, which leads to big problems such as lower productivity and higher soil damage. READ MORE
