  1. 1. Novel steel hinge connection for pedestrian timber bridges : Novel steel hinge connection for pedestrian timber bridges

    University essay from KTH/Byggnadsmaterial

    Author : Charlotte Jaeger; [2023]
    Keywords : ;

    Abstract : This study focuses on exploring a novel timber-to-timber joint using a steel hinge connection (in this work also referred to as door-hinge joint) for pedestrian timber bridges. To conduct the cross-section design of the structural bridge members, a numerical model was developed to determine the internal forces. READ MORE

  3. 2. Development of a Method to Determine the Influence of Rubber Components in Dynamic Simulations

    University essay from KTH/Farkostteknik och Solidmekanik

    Author : Mårten Vuorinen; [2022]
    Keywords : ;

    Abstract : In order to make sure that an engine can withstand the vibration loads, while the weight is kept as low as possible, some components on the engine are made of rubber. The stiffness of these rubber components are several orders of magnitude lower than the surrounding metal components, and the inclusion of rubber components affects the dynamic behaviour of the engine.

  4. 3. Planetary Gear Analysis : deformation induced misalignment and optimization

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Jonsson; [2020]
    Keywords : FEM; gears; KISSsoft; misalignment; planetary gears; FEM; KISSsoft; kugghjul; planetväxlar; vinkelfel;

    Abstract : A handheld heavy-duty nut runner, commonly used to assemble windmills and oil pipe lines, and capable of producing 4100 Nm of torque, experiences low cycle fatigue and usually fails after 20 000 cycles at the specified torque. A full assembly Finite element model of the last stage of the four-stage planetary gearbox is constructed and simulated over one complete load cycle. READ MORE

  5. 4. Numerical analysis of connection in wind turbine rotor blade

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Albin Ingmarsson; [2017]
    Keywords : fibre reinforced composite; truss structure; lightweight; renewable energy; wind turbines; rotor blades; adhesive; finite element method; Technology and Engineering;

    Abstract : A globally growing population, an increased energy consumption and growing environmental awareness have made the interest for renewable energy sources, such as wind power, higher. As a result of the increased demand the need for new and improved technologies have increased. READ MORE

  6. 5. Dynamic analysis of soil-steel composite railway bridges : FE-modeling in Plaxis

    University essay from KTH/Bro- och stålbyggnad

    Author : Orod Aagah; Siavash Aryannejad; [2014]
    Keywords : Soil-steel composite bridge; Corrugated steel culvert; High-speed railways; FEM; Plaxis; Field measurements;

    Abstract : A soil-steel composite bridge is a structure comprised of corrugated steel plates, which are joined with bolted connections, enclosed in friction soil material on both sides and on the top. The surrounding friction soil material, or backfill, is applied in sequential steps, each step involving compaction of the soil, which is a necessity for the construction to accumulate the required bearing capacity.
