  1. 16. Optimization methods for vehicle body structures

    Författare :Harald Fredricson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis is concerned with the use of optimization methods in the vehicle industry. Numerical optimization has been used with limited extend in the vehicle industry. However, great potential of using optimization methods has been identified during the development process of vehicle body structures. LÄS MER

  3. 17. Simulation of bending and hydroforming : constitutive modeling and failure prediction

    Författare :Mikael Jansson; Linköpings universitet; []
    Nyckelord :hydroforming; anisotropy; aluminium; finite element simulation; forming limits;

    Sammanfattning : In recent years, the automotive industry has shown increased interest in reducing weight and improving environmental effects of cars. This has lead to an increased use of lightweight parts. LÄS MER

  4. 18. Behaviour and material properties of composites for crash modelling

    Författare :Thomas Bru; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon fibre composite; non-crimp fabric; crushing; mechanical testing.;

    Sammanfattning : The transport industry must find solutions to reduce its impact on climate change. A promising way to reduce the weight of vehicles and therefore to reduce the CO2 emissions is to introduce components made of lightweight composite materials, in particular laminated carbon fibre reinforced polymers (CFRPs).

  5. 19. Tracking and decision making for automotive collision avoidance

    Författare :Jonas Jansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of the present work is to find a stable and effective optimization algorithm that can be used to determine the location and size of drawbeads in sheet metal forming processes. The result from the optimization will be the restraining force that each drawbead applies to the blank. LÄS MER
