    Author : Mathias Wärja; Torsten Cegrell; Per Lamell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residual lifetime estimation; maintennance management; technical systems in power and pulp- and paper industries; long terms maintenance strategies; Industrial engineering and economy; Industriell teknik och ekonomi;

    Abstract : For complex technical systems in the electricity and pulp and paper industries, maintenance management addresses how to exploit physical assets in the most profitably way. This is a difficult task that requires taking into consideration parameters of totally different natures – e.g. READ MORE

  4. 2. Friction and temperature characteristics of wet clutch engagement

    Author : Mikael Holgerson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : För att erhålla mjukare växlingsförlopp och samtidigt få lång livslängd på våta kopplingar i automatväxellådor krävs förbättrad konstruktion. För att förbättra konstruktionen behövs mer kunskap om inkopplingsförloppet av våta kopplingar. En testrigg för att undersöka inkopplingsförloppet har byggts. READ MORE

  5. 3. Cell wall bulking and distribution of different chemicals in pine, Pinus Sylvestris

    Author : Lennart Wallström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : The interaction between wood, Pinus sylvestris, (60% RH) and polyethyleneglycol (PEG) of different molecular weights (PEG 200 and PEG 1500), pentaerythritol and glycerol, impregnated into the wood, has been investigated using Scanning Electron Microscopy, EDS-analysis, dynamical mechanical techniques (DMTA), X-ray diffraction (WAXS) and macroscopic dimensional measurement. Reduced dimensional changes after impregnation when exposed to environments with changing moisture content, showed that the stabilization effect of glycerol and PEG 200 impregnation is very good.
