  1. 1. Gear Rolling for Production of High Gears

    Författare :Alireza Khodaee; Arne Melander; Stefan Björklund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - Production; SRA - Produktion; Production Engineering; Industriell produktion;

    Sammanfattning : Gears are used to transmit mechanical workfrom one point to another. They are widely used in different mechanisms and they are the most important components of a transmission system. Thus, it is important that they are manufactured with high precision to deliver the work with highest possible efficiency. LÄS MER

  3. 2. Criteria for Machinability Evaluation of Compacted Graphite Iron Materials : Design and Production Planning Perspective on Cylinder Block Manufacturing

    Författare :Anders Berglund; Cornel Mihai Nicolescu; Leonardo De Chiffre; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Cutting; Compacted Graphite Iron CGI ; Machinability; Design of Experiments DoE ; Inverse Finite Element FE Modelling; Simulated Milling Method; SRA - Produktion; SRA - Production;

    Sammanfattning : The Swedish truck industry is looking for new material solutions to achieve lighter engines with increased strength to meet customer demands and to fulfil the new regulations for more environmentally friendly trucks. This could be achieved by increasing the peak pressure in the cylinders. LÄS MER

  4. 3. Information Management for Factory Planning and Design

    Författare :Danfang Chen; Torsten Kjellberg; Terje Kristoffer Lien; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - Production; SRA - Produktion;

    Sammanfattning : This thesis is dedicated to the manufacturing industry for the improvement of information management within the factory planningand design domain, and for more efficient factory planning and design. Currently the manufacturing industry lacks sufficient methods for capturing, structuring, and representing information and knowledge for easy access, exchange, integration and reuse within the domain.

  5. 4. An Analysis of the Proactive Approach as a Potential Tool for Adaptability in Production Systems

    Författare :Kerstin Dencker; Mauro Onori; Lena Mårtensson; Monica Bellgran; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assembly; production system design; proactivity; human-machine collaboration; SRA - Production; SRA - Produktion;

    Sammanfattning : Competitive systems for manufacturing, especially assembly systems, have to cope with frequent changes of external as well as internal demands. A proactive behaviour in an assembly system should make it capable of rapid changes and have an ability to handle frequent changes and disturbances. LÄS MER

  7. 5. Reactions of aqueous radiolysis products with oxide surfaces : An experimental and DFT study

    Författare :Cláudio Miguel Lousada Patrício; Mats Jonsson; Jean-Philippe Renault; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogen peroxide; hydrogen production; metal; oxides; lanthanide; catalysis; density functional theory; surface; reactions; chemistry; SRA - Energy; SRA - Energi; SRA - Production; SRA - Produktion;

    Sammanfattning : The reactions between aqueous radiolysis products and oxide surfaces are important in nuclear technology in many ways. In solid-liquid systems, they affect (and at the same time are dependent on) both the solution chemistry and the stability of materials under the influence of ionizing radiation. LÄS MER
