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

    Abstract : Wet clutches are used in a variety of machinery such as in vehicles where they are used to distribute torque in the drivetrains. Clutches can be located in automatic transmissions or in limited slip differentials. READ MORE

  5. 3. Intelligent fault diagnosis and predictive maintenance for a bearing ring grinder

    Author : Muhammad Ahmer; Pär Marklund; Fredrik Sandin; Kim Berglund; Martin Gustafsson; Peter Krajnik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analysis; grinding machines; diagnostics; predictive maintenance; condition monitoring; intelligent fault diagnosis; Maskinelement; Machine Elements;

    Abstract : Predicting the failure of any structure is a difficult task in a mechanical system. However complicated and difficult the prediction might be, the first step is to know the actual condition of the system. READ MORE

  6. 4. Transient elastohydrodynamic lubrication : Effects of geometry, surface roughness, temperature, and plastic deformation

    Author : Tobias Hultqvist; Roland Larsson; Pär Marklund; Wassim Habchi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The urgent need to reduce greenhouse gas emissions in combination with an increased use of sustainable energy resources have led to immense efforts on improving energy efficiency of mechanical systems. Consequently, modern machine elements are typically lubricated with low viscosity oils and designed to endure an increasingly high power density. READ MORE

  7. 5. Towards model-based development of heavy truck synchronizers

    Author : Daniel Häggström; Ulf Sellgren; Pär Marklund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox;

    Abstract : Gear shifts are becoming more and more important as engines are adapted to low speed and high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to future engines and thus new working conditions, improved development tools are needed. READ MORE
