  1. 36. Structural Design of Laser-Welded Sandwich Panels for Marine Applications

    Författare :Hans Kolsters; KTH; []
    Nyckelord :Sandwich; Laser welding; Web; Core; Stiffness; Elastic Buckling; Ultimate strength; Finite element analysis; Mechanical testing; Optimisation.;

    Sammanfattning : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.

  3. 37. Traffic Situation Management for Driving Automation of Articulated Heavy Road Transports - From driver behaviour towards highway autopilot

    Författare :Peter Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver model; driving simulator; driving principles; driving automation; vehicle model; articulated heavy-vehicles; vehicle dynamics; long combination vehicles;

    Sammanfattning : In this thesis traffic situation management for driving automation of long combination vehicles is discussed. The automation targets high-speed driving in multiple-lane, one-way roads. Traffic situation predictions, traffic situation manoeuvres and driving principles are studied specifically. LÄS MER

  4. 38. Simulation-Driven Design of Complex Mechanical and Mechatronic Systems

    Författare :Johan Wall; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exhaust system; Experimentation; Machine tools; Mechatronics; Optimisation; Product development; Prototyping; Simulation; Structural dynamics;

    Sammanfattning : Effective and efficient product development is critical to business success on the increasingly competitive global market, and simulation has proven to support this in many sectors. The aim of this thesis is to study how properties of complex mechanical and mechatronic systems can be more efficiently and systematically predicted, described, assessed and improved in product development.

  5. 39. A Thermoeconomic Evaluation of CO2 Capture with Focus on Gas Turbine-Based Power Plants

    Författare :Björn Fredriksson Möller; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; climate change; optimisation; genetic algorithms; applied thermodynamics; Thermal engineering; AZEP; GTPOM; gas turbine; CO2 capture; thermoeconomy; termodynamik;

    Sammanfattning : The increasing emissions of carbon dioxide from fossil fuel burning are today thought to be one of the main contributors to global warming. At the same time, developing countries are striving for an increased welfare and burning more fossil fuel, which in turn is augmenting the greenhouse gas effect. LÄS MER

  7. 40. Network Modelling of Port Terminals Development of a Concept and a Tool

    Författare :Karl Jansen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combinatorial graph theory; optimisation; port terminals; complex node functionalities; modelling of information; implementation of a tool;

    Sammanfattning : Network theory can be used to model and optimise logistic systems. The movement of goods is a major issue in our society and there is a large potential for increased efficiency in the transportation systems. Terminals and their equivalents are important in logistic systems. This is especially obvious when it comes to sea transport. LÄS MER
