  1. 1. Glulam timber arches Strength of splices and reliability-based optimisation

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Nils Olsson; Mittuniversitetet.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik; Timber Arches; Glulam; Reliability; Optimisation; Reliability-based optimisation; Träbyggnad; Timber Structures;

    Sammanfattning : Arch structures are very sensitive to changes in the distribution of the load as well as to changes in their shape. A slight change in the load distribution may imply internal forces for which the arch is not designed. LÄS MER

  2. 2. Optimization of Vehicle Structures under Uncertainties

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Sandeep Shetty; Linköpings universitet.; Linköpings universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiobjective optimisation; robustness analysis; robust design optimisation; reliability-based optimisation; crashworthiness; metamodel;

    Sammanfattning : New emission targets, increased safety requirements and competition in the global market have led the automotive industry to focus more on developing efficient, optimised vehicle structures. Consequently, the use of simulation-based design in vehicle engineering has increased significantly in recent years. LÄS MER

  3. 3. An Integration-Reduction Scheme for Simulation of Large Systems with Local Nonlinearity and Uncertainty - Application to moving load problems in railway mechanics

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Sadegh Rahrovani; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte-Carlo simulations; time-integration; moving load problems; reliability analysis; exponential integrator; symplectic integrator; modal dominancy analysis;

    Sammanfattning : The focus of this research is mainly on computational efficiency, as future work is planned for reliability analysis that will be combined with design optimisation. Both these fields are known to be notoriously computationally demanding. LÄS MER
