  1. 11. Development, application, and reliability of methods for ergonomic workload assessments in production evaluation and workstation design

    Författare :Ida-Märta Rhen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Work-related Musculoskeletal Disorders; Risk assessment; Direct measurement; Biomechanical Exposure; Systematic Observation; Digital Human Modelling; Ergonomics; Workplace Design; Simulation; Reliability;

    Sammanfattning : Ergonomics assessments of conditions for humans at workstations and in manufacturing processes are necessary to prevent work-related musculoskeletal disorders and enhance efficiency and quality. Many methods can be used for this from systematic observations to direct measurements and simulation. LÄS MER

  3. 12. Heat and water transfer for lacquer drying and thermal signatures : modelling, simulation and experiment

    Författare :Ricardo Garcia-Padron; Roland Wimmerstedt; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The coupled phenomenon of heat and water transfer is essential in many scientific and industrial problems. This thesis focuses this phenomenon on two areas; lacquer drying and thermal signatures. Simulations of physical phenomena may in some cases replace extensive experimental investigations, which may be complicated and expensive. LÄS MER

  4. 13. Discrete Element Modelling and Simulation of Vibratory Screens

    Författare :Ali Davoodi; 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; Screen efficiency; Modelling.; DEM simulation;

    Sammanfattning : In Sweden about 85 million tonnes aggregate is used for road, railway and concrete every year. Crushing is the main process for producing the aggregate material in different fractions. The crushing process is divided into two sub-processes; comminution and separation. LÄS MER

  5. 14. Compression moulding of SMC : experiments and simulation

    Författare :Jimmy Olsson; Daniel Ståhlberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Due to excellent properties and relatively low material and manufacturing costs, the use of fibre reinforced polymer composites have increased during the last decades. One method that is suitable for large scale productions of e.g. lightweight vehicle components is compression moulding of sheet moulding compound (SMC). LÄS MER

  7. 15. Uncertainty and Robustness in Aerospace Structures

    Författare :Anders Forslund; 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; simulation; geometry assurance; robust design; Geometrical variation; uncertainty quantification;

    Sammanfattning : Engineering is not an exact science. In fact, all engineering activity contain some degree of assumption, simplification, idealization, and abstraction. When engineered creations meet reality, every manufactured product behaves differently. This variation can be detrimental to product quality and functionality. LÄS MER
