  3. 2. Influence of combined thermal and mechanical loadings on pearlitic steel microstructure in railway wheels and rails

    Författare :Dimitrios Nikas; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low cycle fatigue LCF ; Wheel steels; Hardness; TEM; Thermal effects; EBSD; Rail steels; Pearlite; Multiaxial fatigue; Spheroidisation; Materials Science;

    Sammanfattning : One of the most important aspects in railway operation is the interaction between rail and wheel. The contact patch between these two components is around the size of a small coin, and since high loads act on this small area, stresses will give rise to wear and damage in both components. LÄS MER

  4. 3. Human-centred design for maritime technology and organizational change

    Författare :Nicole Almeida Costa; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; participatory ergonomics; organizational change; technology acceptance; digitalization; systems theory; e-Navigation; human-centred design;

    Sammanfattning : Context: The shipping industry is undergoing a transitional phase at different levels, including IMO’s e-Navigation initiative, and with this comes the need to use a human-centred design (HCD) approach to avoid accidents linked to automation issues, and to cater for the maintenance of safety and efficiency within this global transport system. Aims: The aim of this thesis is to investigate the value and challenges in HCD practice and how ergonomics/human factors (E/HF) principles can be introduced, as well as what gaps and opportunities exist in current standard operations and technologies in navigation that can potentially be followed upon by future e-Navigation developments, not only from a technological perspective but also regulatory, operational etc. LÄS MER

  5. 4. Polishability of tool steels : Characterisation of high gloss polished tool steels

    Författare :Sabina Rebeggiani; Olaf Dambon; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steels; surface characterisation; polishability; 3D parameters; high gloss polishing; Surface engineering; Ytbehandlingsteknik;

    Sammanfattning : The manufacturing of plastic components, like a majority of other mass produced discrete parts, require well designed dies and moulds. Complex geometries and increasing demands on final surface appearance, which is strongly connected to the quality impression, are pushing for high demands on mould-makers and polishers as well as steel producers.
