  1. 21. Modelling of Traffic Loads on Bridges Based on Measurements of Real Traffic Loads in Sweden

    Författare :Fredrik Carlsson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy vehicles; traffic intensity; Peaks Over Thresholds; axle and bogie pressure; traffic load effects; probability based classification; Technological sciences; Teknik;

    Sammanfattning : This thesis treats traffic load effects in road bridges and in particular bending moment and shear force in different types of bridges. All traffic load effects are described in terms of statistical distribution functions for annual extreme values. LÄS MER

  3. 22. Loads and responses for planing craft in waves

    Författare :Anders Rosén; Dan Zenker; Brian Hayman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; planing craft; high-speed craft; waves; model tests; sull-scale trials; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Experimental and numerical analysis of loads and responses for planing craft in waves is considered. Extensive experiments have been performed on a planing craft, in full-scale as well as in model scale. The test set-ups and significant results are reviewed. LÄS MER

  4. 23. EMC Aspects of PMW Controlled Loads in Vehicles

    Författare :Sabine Marksell; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The number of electrically driven loads in a modern vehicle is constantly increasing. Many loads that former were mechanically driven will in the future be driven by electricity. This implies that a number of electronic systems have to be packed together in the limited space in a vehicle. LÄS MER

  7. 25. Prediction of engine component loads using previous measurements

    Författare :Pär Mikaelsson Elmén; Mårten Olsson; Jan-Olov Aidanpää; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine; engine block vibration; engine block twist; engine block bending; vibration measurement; vibration estimation; rigid body vibrations; assumed modes; bending modes; torsion modes; system modification; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Internal combustion engines are used in many applications. The same engine type may have different components mounted to it depending upon its use. These engine mounted components need to be designed against fatigue in order to withstand the engine vibrations. Measured engine vibrations are commonly used as input data for fatigue estimation.
