1. 6. Structuring and use of motion data for computer manikin work task simulations

   Författare :Ali Keyvani; Roland Örtengren; D. Lämkull; Gunnar Bolmsjö; Keith Case; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Human Modelling; Computer Manikins; Motion Capture Data Management; Virtual Production Tools; Human Motion Simulation; Motion Synthesis; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Modelling and simulation of human motions are of great interest for a number of industrial applications such as ergonomics and production planning. Over time, efforts have been made to provide computerized human models with biomechanically accurate underlying skeleton and realistically rendered volumetric representation of muscles, skin, clothes, etc. LÄS MER

3. 7. Thermo-electric temperature measurements in friction stir welding : Towards feedback control of temperature

   Författare :Ana Magalhães; Gunnar Bolmsjö; Jeroen De Backer; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FSW; Robotic; Temperature; TWT; Plunge; Control; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. LÄS MER

4. 8. Dissimilar joining of aluminium to ultra-high strength steels by friction stir welding

   Författare :Wallop Ratanathavorn; Arne Melander; Gunnar Bolmsjö; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium alloy; high strength steel; intermetallic; friction stir welding; dissimilar joining; SRA - Produktion; SRA - Production;

   Sammanfattning : Multi-material structures are increasingly used in vehicle bodies to reduce weight of cars. The use of these lightweight structures is driven by requirements to improve fuel economy and reduce CO2 emissions. The automotive industry has replaced conventional steel components by lighter metals such as aluminium alloy. LÄS MER

5. 9. Simulation-based feedback control of welding processes

   Författare :Fredrik Sikström; Bengt Lennartson; Gunnar Bolmsjö; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element modelling; Heat transfer; Model order reduction; Sensors; Weld simulation Controller design; Automatic control; Reglerteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Fusion welding for joining of metals is an important manufacturing process widely used in industry, and very appreciated for its usefulness. This thesis presents a strategy dealing with the problem of designing feedback control for robotised welding. LÄS MER

7. 10. Configuration Design of a High Performance and Responsive Manufacturing System : Modeling and Evaluation

   Författare :Daniel Tesfamariam Semere; Bengt Lindberg; Bolmsjö Gunnar; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Configuration; Modeling; Evaluation; Manufacturing engineering; Produktionsteknik;

   Sammanfattning : Configuring and reconfiguring a manufacturing system is presented as an issue with increasing importance due to higher frequency of system configuration or major reconfigurations to accommodate new set of requirements and/or the need to configure the system to make it usable across generations of products or product families. This research has focused in the modeling, evaluation and selection decisions which involves multiple, incommensurate and conflicting objectives. LÄS MER
