1. 1. Tracked vehicles : the influence of design parameters on the tractive performance in deep snow

   Författare :Anders Bodin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Sammanfattning : To increase the mobility of tracked vehicles in deep snow with the payload capacity preserved and the maintenance costs kept low, improved design is required. To optimise new tracked vehicles intended to operate in deep snow, more knowledge about the vehicle design parameters that affect the tractive performance in deep snow is needed, especially regarding the design of the track assembly and of the vehicle belly.

4. 3. Suspended forestry machines for sustainable forestry

   Författare :Abbos Ismoilov; Ulf Sellgren; Kjell Andersson; Viktor Berbyuk; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

   Sammanfattning : Cut-to-length (CTL) logging is a mechanized two-machine solution. The harvester processes treestems into smaller logs and a forwarder transports the logs from the logging site to a landing areaaccessible by trucks. LÄS MER

5. 4. On forestry machine and soil interaction for sustainable forestry

   Författare :Abdurasul Pirnazarov; Ulf Sellgren; Kjell Andersson; Iwan Wästerlund; KTH; []

   Sammanfattning : More than 50 percent of the land area of the Nordic countries Finland, Norway, and Sweden are covered by dense forests and they are among the most important producers of forest products in the world. Forestry in these countries is based on sustainable management principles – reforestation follows harvesting. LÄS MER

7. 5. Improving the mobility performance of tracked vehicles in deep snow

   Författare :Anders Bodin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Sammanfattning : Improving the mobility of tracked vehicles in deep snow requires an increase in the knowledge and understanding of the design parameters which influence the tractive performance. This relates particularly to the new vehicle requirements of increased payload to vehicle weight ratio, improved fuel economy and reduced life cycle costs. LÄS MER
