  1. 1. Dynamic Soil-Structure Interactionof Soil-Steel Composite Bridges : A Frequency Domain Approach Using PML Elements and Model Updating

    University essay from KTH/Bro- och stålbyggnad

    Author : DIEGO FERNANDEZ BARRERO; [2019]
    Keywords : Dynamics; soil-steel bridges; soil-structure interaction; model updating; PML; particle swarm; corrugated steel plates; frequency domain assurance criteria; parallel computing 2;

    Abstract : This master thesis covers the dynamic soil structure interaction of soil-steel culverts applyinga methodology based on the frequency domain response. At the first stage of this masterthesis, field tests were performed on one bridge using controlled excitation. READ MORE

  2. 2. Developing a Virtual Consumer: From Human Skin to FE Modelling

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Viktor Hultgren; Gustaf Svanberg; [2019]
    Keywords : FEM; Skin; Dermis; Motion Capture; Technology and Engineering;

    Abstract : In the 'on-the-go' society of today, the use of single unit beverage packages has increased. Consequently, the interaction between the consumer and the package have also attracted greater interest when trying to gain advantages in a competitive market. READ MORE

  3. 3. Evaluation of 3D dynamic effects induced by high-speed trains on double-track slab bridges

    University essay from KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Author : Jossian Thomas; Assís Arañó Barenys; [2016]
    Keywords : Dynamics; Frequency analysis; 3D model; Torsional modes of vibration;

    Abstract : In addition to a static design, a dynamic analysis has to be performed for bridgesfor which the maximum permissible train speed exceeds 200 km/h. This analysisrequires a lot of computing time, for this reason Svedholm and Andersson (2016)have developed a simple tool describing the relationship between the first eigenfrequencyof the bridge, the span length and the minimum mass to fulfill the regulationspecified in EN-1990.

  4. 4. Investigation of cracking due to restraint forces in Swedish concrete slab frame bridges

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Robin Almen; [2016]
    Keywords : slab frame bridges; concrete cracking; crack control; restraint; restraint forces; finite element; Technology and Engineering;

    Abstract : When concrete slab frame bridges are designed with modern linear 3D FE-models large tensile restraint forces will arise in the transversal direction of the bridge from the temperature and shrinkage loads. These restraint forces are much larger than those that are accounted for in the older 2D models. READ MORE

  5. 5. Magnet Losses in Inverter-fed High-speed PM Machines

    University essay from KTH/Elektrisk energiomvandling

    Author : Adolfo Garcia Gonzalez; [2015]
    Keywords : Eddy currents; FEM 2D; FEM 3D; magnet losses; nut-runner; PM motor; slot-less winding; Virvelstrommar; FEM 2D; FEM 3D; forluster i magneter; mutterdragare; permanentmagnetiserad motor; luftlindad lindning;

    Abstract : This master thesis deals with the estimation of magnet losses in a Permanent Magnet(PM) motor inserted in a nut-runner. This type of machine has interesting featuressuch as being slot-less and running at a very high speed (30000 rpm). READ MORE
