  1. 36. Extended Application of Robust Design Methodology

    Författare :Vanajah Siva Subramaniam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; practices; life cycle approach; Robust design methodology; back-end data; sustainable product development;

    Sammanfattning : Robust Design Methodology (RDM), a subset of Quality Management (QM), is an approach applied to the design phase of product development in order to manage variability in product performance by creating insensitivity to noise factors. Noise factors are sources of variation that cannot be readily controlled. LÄS MER

  3. 37. Development of Accurate Reduced Order Models in a Simulation Tool for Turbomachinery Aeromechanical Phenomena

    Författare :Mauricio Gutierrez Salas; Björn Laumert; Paul Petrie-Repar; Damian Vogt; Carlos Martel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flutter; forced response; high cycle fatigue; reduced order models; ROM; craig-bampton; mistuning; tuned; mistuned; cyclic; noncyclic; craig-chang; free-interface. fixed-interface; subset nominal mode; SNM; CBMS; CCMS; CCC; CBC; FEM; CMS; modal; eigen; modeshapes; aeroelasticity; aeromechanical; tool; turbomachinery; turbine; compressor; AROMA; Energy Technology; Energiteknik;

    Sammanfattning : Modern gas turbines are still vulnerable to vibrations when operated at certain speeds. This unstable environment can lead to high cycle fatigue (HCF) and damage several of the components inside the turbine. LÄS MER

  4. 38. Joining of Carbon Fibre Reinforced Plastics for Automotive Applications

    Författare :Gordon Kelly; KTH; []
    Nyckelord :Composite; laminate; bearing strength; joining; load introduction; hybrid joint; finite element analysis; mechanical testing;

    Sammanfattning : The introduction of carbon-fibre reinforced plastics in loadbearing automotive structures provides a great potential toreduce vehicle weight and fuel consumption. To enable themanufacture and assembly of composite structural parts,reliable and cost-effective joining technologies must bedeveloped. LÄS MER

  5. 39. Assessment of Concrete Structures Including Corrosion and Cracks

    Författare :Mattias Blomfors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforced concrete; corrosion; nonlinear FE analysis; reinforcement bond; assessment; cracks;

    Sammanfattning : Reinforced concrete (RC) structures constitute a major proportion of the built environment and society relies continuously on their service. Many of these structures were built in the era following the Second World War and are thus approaching the end of their intended service life. LÄS MER

  7. 40. Design, Simulation and Characterization of Some Planar Lightwave Circuits

    Författare :Yaocheng Shi; Anand Srinivasan; Sailing He; Daniel Erni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; planar lightwave circuit; waveguide; coupler; multimode interference; photonic crystal waveguide; de multiplexer; triplexer; polarization beam splitter; dry etching; carrier life time.; Photonics; Fotonik;

    Sammanfattning : Optical devices based on planar lightwave circuit (PLC) technology have the advantages of small size, high reliability, possibility for large scale production, and potential integration with electronics. These devices are widely employed in optical telecommunications, sensing, data storage, imaging, and signal processing. LÄS MER
