  1. 21. Optimized wet clutches : simulation and tribotesting

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

    Sammanfattning : Wet clutches are used in a variety of different machinery. Wet clutches and brakes are frequently used to distribute torque in vehicle drive-trains. The clutches can be located in e.g. LÄS MER

  3. 22. Nonlinear Model Predictive Control for Autonomous Vehicles

    Författare :Paolo Falcone; Universita degli Studi del Sannio; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis we consider the problem of designing and implementing Model Predictive Controllers (MPC) for stabilizing the dynamics of an autonomous ground vehicle. For such a class of systems, the non-linear dynamics and the fast sampling time limit the real-time implementation of MPC algorithms to local and linear operating regions. LÄS MER

  4. 23. Wet clutch tribological performance optimization methods

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

    Sammanfattning : 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. LÄS MER

  5. 24. Bonded Particle Model for Jointed Rock Mass

    Författare :Diego Mas Ivars; Joanne MR Fernlund; John Harrison; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bonded particle model; Smooth-joint contact model; Discrete fracture network; Synthetic rock mass; Jointed rock mass; Geoengineering; Geoteknik;

    Sammanfattning : Jointed rock masses are formed of intact rock and joints. There-fore, proper characterization of rock mass behavior has to consid-er the combined behavior of the intact rock blocks and that of the joints. This thesis presents the theoretical background of the Synthetic Rock Mass (SRM) modeling technique along with example applica-tions. LÄS MER

  7. 25. On truck tyre modelling

    Författare :Boris Thorvald; KTH; []
    Nyckelord :;

    Sammanfattning : A physically based 3D tyre model with transient propertiesand reasonable computational effort is presented. Basic dynamitbehaviour is considered with the tyre belt modelled as a rigidring. LÄS MER
