  1. 21. On aircraft fuel systems : conceptual design and modeling

    Författare :Hampus Gavel; Petter Krus; Johan Ölvander (Andersson); Dieter Scholz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft; morphological matrix; simulation; Saab; Gripen; Construction engineering; Konstruktionsteknik;

    Sammanfattning : The largest and most important fluid system in an aircraft is the fuel system. Obviously, future aircraft projects involve the design of fuel system to some degree. In this project design methodologies for aircraft fuel systems are studied, with the aim to shortening the system development time. LÄS MER

  3. 22. Constructive cooperative coevolution for optimising interacting production stations

    Författare :Emile Glorieux; Bengt Lennartson; Fredrik Danielsson; Bo Svensson; Johan Ölvander; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing automation; metaheuristic optimasion algorithm; optimised production technology; algorithm design and analysis; interacting production stations; sheet metal press lines; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Engineering problems have characteristics such as a large number of variables, non-linear, computationally expensive, complex and black-box (i.e. unknown internal structure). These characteristics prompt difficulties for existing optimisation techniques. LÄS MER

  4. 23. On Safe Collaborative Assembly With Large Industrial Robots

    Författare :Varun Gopinath; Kerstin Johansen; Johan Ölvander; Micael Derelöv; Michael Hofbaur; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis pertains to industrial safety in relation to human-robot collaboration. The aim is to enhance understanding of the nature of systems where large industrial robots collaborate with humans to complete assembly tasks. This understanding may support development and safe operations of future collaborative systems. LÄS MER

  5. 24. Low-Cost Demonstrators : Enhancing Product Development with the Use of Physical Representations

    Författare :Peter Hallberg; Johan Ölvander; Petter Krus; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Ever since the early nineties and the advent of affordable and comprehensive 3D-CAD systems, companies have striven to take advantage of cost-effective Virtual Prototyping, gradually moving away from activities involving physical representations of the evolving product. There are, however, aspects of the product development process that are less suitable for virtual exploration. LÄS MER

  7. 25. Introducing New Materials in the Automotive Industry : Managing the Complexity of Introducing New Materials in Existing Production Systems

    Författare :Fredrik Henriksson; Kerstin Johansen; Jonas Detterfelt; Johan Ölvander; Mats Winroth; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Passenger vehicles are central to Western society, and contribute to a significant part of our greenhouse gas emissions. In order to reduce emissions, the automotive industry as a whole is working to reduce mass in passenger vehicles in order to reduce energy consumption. LÄS MER
