  1. 21. Evaluating the Effects of Variation on Product Appearance through Visual Robustness

    Författare :Karin Nordvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; product experience; visual quality appearance; visual sensitivity; optical quality; industrial design; perceived quality; craftsmanship; robust design; non-nominal visualization; geometrical variation; visual robustness;

    Sammanfattning : For consumer products where the product appearance plays an important role in meeting expectations, the visible effects of manufacturing variation can have a negative influence on the product experience. A concomitant of mass production is that no manufactured units are exactly identical, as a result of variation. LÄS MER

    Sammanfattning : For consumer products where the product appearance plays an important role in meeting expectations, the visible effects of manufacturing variation can have a negative influence on the product experience. A prerequisite in mass production is that no manufactured units are exactly identical, as a result of variation. LÄS MER

  4. 23. Design for Producibility in Fabricated Aerospace Components - A framework for predicting and controlling geometrical variation and weld quality defects during multidisciplinary design

    Författare :Julia Madrid; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quality Assurance; Welding; Aerospace; Design for Producibility; Welding simulation; Variation Management; Design for Manufacturing; robust design;

    Sammanfattning : In the aerospace industry, weight reduction has been one of the key factors in making aircraft more fuel efficient in order to satisfy environmental demands and increase competitiveness. One strategy adopted by aircraft component suppliers to reduce weight has been fabrication, in which small cast or forged parts are welded together into a final shape. LÄS MER

  5. 24. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors

    Författare :Andreas Abdon; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motors and propulsion systems; plasma; combustor; gas turbine; cooling; numerical simulations; turbulence; ribs; impingement; Gases; fluid dynamics; plasmas; fluiddynamik; Gaser; Motorer; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

    Sammanfattning : The mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. LÄS MER

  7. 25. How to Reduce Geometrical Variation in Assembled Products

    Författare :Johan Carlson; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; assembled products; body-in-white BIW ; dimensional variation; geometrical variation; fixtures; fixture diagnosis; locating schemes; multivariate analysis; rigid body motion; robust design; root cause; quality; root cause;

    Sammanfattning : Vehicle problems, such as wind noise, water leakage and door closing effort are examples of quality and functionality defects that are controlled by the dimensional accuracy of the structural frame of an auto body. The aim of this thesis is towards methods for reducing geometrical variation in assembled products in the automotiv other industries. LÄS MER
