  1. 6. Tire Modeling and Friction Estimation

    Författare :Jacob Svendenius; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Vehicle Dynamics; Wheel Speed; Brush Model; Combined Slip; Tire Models; Teknik; Friction Estimation;

    Sammanfattning : New system technologies are continuously improving the performance of vehicles regarding comfort, stability, environmental stresses, and safety. Novel sensors are developed and used together with advanced control algorithms and faster and more accurate actuators to help the driver to maneuver the vehicle in a safer way. LÄS MER

  3. 7. Wet clutch tribology : friction characteristics in limited slip differentials

    Författare :Rikard Mäki; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : In recent years, electronically controlled automotive transmission systems, where wet clutches are used as intelligent differentials, have appeared in the market. These applications impose great demands on the transmission fluids and friction materials used as well as on controllability and vibration preventive (anti-shudder) properties of the clutch systems.

  4. 8. Implementation and Application of Fracture Mechanics Models for Concrete Structures

    Författare :Magnus Åkesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bond slip; concrete cracking; abstract data types; prestressing; enhanced strain;

    Sammanfattning : Two numerical models for simulation of concrete cracking and bond slip have been implemented and applied in various comparative analyses. Both models were implemented in the commercial finite element system ABAQUS. LÄS MER

  5. 9. Optical characterisation of subwavelength dielectric particles using particle tracking beyond the Stokes-Einstein relation

    Författare :Erik Olsén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; off-axis holography; Optical microscopy; size determination; particle tracking; partial slip; lipid vesicles; particle dynamics;

    Sammanfattning : As the importance of nanoparticles continues to increase in both biology and industrial processes, so does the need for accurate and versatile characterisation methods. However, most light-based methods to quantify size and refractive index of individual particles are either limited to snapshot observations, particles larger than the wavelength of light, non-dynamic particle properties, or assuming the hydrodynamic boundary conditions without experimental evaluation.

  7. 10. Particle Filtering and Optimal Control for Vehicles and Robots

    Författare :Karl Berntorp; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle filtering; optimal control; automotive systems; out-of-sequence measurement; autonomy; model predictive control; sensor fusion; wheel slip; dynamic optimization;

    Sammanfattning : This thesis covers areas within estimation and optimal control of vehicles, in particular four-wheeled vehicles. One topic is how to handle delayed and out-of-sequence measurements (OOSMs) in tracking systems. LÄS MER
