  1. 1. Test Design for Finite Element Model Updating - Identifiable Parameters and Informative Test Data

    University dissertation from Chalmers University of Technology

    Author : Andreas Linderholt; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinteknik; Mechanical Engineering; Test Design Finite Element Model Updating Informativeness Identifiability optimization Fisher information modal tests; Teknisk mekanik; Engineering mechanics; model updating; identifiability; data informativeness; test design; optimization; Fisher information; modal tests;

    Abstract : It is important to predict structural phenomena, such as noise and fatigue, stemming from vibra- tions. To do this, reliable structural dynamic models are needed. To be useful the models have to compare well with reality in the validation against test data; if not, the models should be mod- ified. READ MORE

  2. 2. Affective Surface Engineering for Product Design

    University dissertation from Chalmers University of Technology

    Abstract : Design research, sensation and perception, hard metrology, emotional functions, semantics, surface roughness, product interaction, core values, total appearance… the list of scientific phrases never ends. Yet, what do they mean and how shall we use it when we are communicating with the industry and our end users? Is it possible to link the product experience to process parameters, put a number onto it? When you can measure spoken needs or even better, implied needs, of a product, and relate that data to the production, it is possible do create advanced products with high interaction stimuli.

  3. 3. Fundamentals of a Methodology for Predictive Design Analysis

    University dissertation from Lund University

    Author : Martin Eriksson; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Generic design analysis process model; Predictive design analysis; Confidence appraisal activities; Computer-based design analysis; Engineering design; Integration;

    Abstract : The rapid development of computer-based design analysis tools and methods such as the finite element method (FEM) within computational structural mechanics (CSM), computational fluid dynamics (CFD), and multi-body systems (MBS) during recent decades has fundamentally changed the way in which products are designed and developed. Among the many advantages observed in industrial practice, one can mention improved understanding of product properties and behavior, the possibility to optimize critical design parameters and to optimize parts as well as the entire product at a system level, the possibility to explore a design space during the synthesis activity, and a decrease of the need for physical testing and thus of the number of physical prototypes needed.

  4. 4. Planning Design Automation A Structured Method and Supporting Tools

    University dissertation from Göteborg : Department of Product and Production Development, Chalmers University of Technology

    Author : Mikael Cederfeldt; Högskolan i Jönköping.; Högskolan i Jönköping.; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design automation; Planning; Evaluation; Process; Knowledge; Methods; Potential; Need; Teknisk mekanik; Engineering mechanics;

    Abstract : The demand for customised products that meet different markets and different customers is steadily increasing. Also, the demand for shorter lead times for the delivery of these customised products puts strains on design departments whose work tends to become increasingly repetitive. READ MORE

  5. 5. Tool steel for tool holder applications microstructure and mechanical properties

    University dissertation from Karlstad : Karlstad University

    Author : Anna Medvedeva; Karlstads universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; tool steel; tool holder; microstructure; mechanical properties; machinability;

    Abstract : Large improvements in cutting tool design and technology, including the application of advanced surface engineering treatments on the cemented carbide insert, have been achieved in the last decades to enhance tool performance. However, the problem of improving the tool body material is not adequately studied. READ MORE
