  1. 1. Development of Dynamic Test Method and Optimisation of Hybrid Carbon Fibre B-pillar

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emil Johansson; Markus Lindmark; [2017]
    Keywords : Dynamic test method; B-pillar; Crash worthiness; Side impact crash test; IIHS; Carbon fibre reinforced polymer composite; Composite failure; CFRP; UD; 2x2 Twill; Delamination; Finite Element Method; LS-Dyna; Steel-composite interface; Bilinear fracture toughness;

    Abstract : The strive for lower fuel consumption and downsizing in the automotive industry has led to the use of alternative high performance materials, such as fibre composites. Designing chassis components with composite materials require accurate simulation models in order to capture the behaviour in car crashes. READ MORE

  3. 2. Journal Bearing Friction Optimization

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Szerena - Krisztina Ujvari; [2016]
    Keywords : tibology; engine main bearings; friction and wear; optimization;

    Abstract : Engine downsizing, improving fuel efficiency while satisfying the environmental legislations are one of the main driving forces in developing new solutions for passenger cars.Engine main bearings, are journal bearings which support the crankshaft and operate principally in full film lubrication.

  4. 3. Simulation and Testing of Energy Efficient Hydromechanical Drivlines for Construction Equipment

    University essay from Linköpings universitet/Fluida och mekatroniska system; Linköpings universitet/Tekniska högskolan

    Author : Viktor Larsson; L. Viktor Larsson; [2014]
    Keywords : hydraulic; power-split; hydrostatic; PST; HST; mechatrinics; oil; volvo; backhoe; transmission; harware-in-the-loop; simulation; hopsan; control; PID; feed forward; HWIL; fluid power; Hydraulik; power-split; hydrostat; PST; HST; mekatronik; olja; volvo; backhoe; transmission; harware-in-the-loop; simulering; hopsan; reglering; PID; framkoppling; HWIL;

    Abstract : Increased oil prices and environmental issues have increased a need of loweringthe emissions from and the fuel consumption in heavy construction machines. Anatural solution to these issues is a lowered input power through downsizing ofthe engine. READ MORE

  5. 4. Coordinated Model Based Thottle and Turbo Control

    University essay from Fordonssystem; Tekniska högskolan

    Author : Petter Carlsson; [2013]
    Keywords : MVEM; Turbocharge; Oscillation; Compensation control;

    Abstract : Downsizing and turbocharging is one way to meet the high demands on fuel consumptionand performance on todays engines. The air-path system in a turbochargedspark ignited engine is a complex system and because the intake manifoldpressure is tightly connected with the engine torque a consistent and robustcontrol is needed.

  6. 5. Growing Tiny Houses: Motivations and Opportunities for Expansion Through Niche Markets

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Amelia Mutter; [2013]
    Keywords : Tiny houses; compact housing; sustainable consumption; niche markets; technological transition; Earth and Environmental Sciences;

    Abstract : The increase in population and urbanization has led to widespread concern about the resulting volume of consumption. This is especially problematic in the housing market, where home size continues to grow. In the United States the average size of a single-family home has doubled since 1950, leading to a profound environmental impact. READ MORE
