  1. 21. Simulation of manufacturing processes in product development

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Peter Åström; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : In the manufacture of aero engine components, three key manufacturing processes can be identified. These are welding, heat treatment and mechanical cutting. Depending on what is required in terms of mechanical- and geometrical properties in the final product these processes are typically combined in a certain sequence. LÄS MER

  2. 22. Simulation of welding and stress relief heat treating in the development of aerospace components

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Daniel Berglund; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : It is important to control critical dimensions of aero engine components during the manufacturing process in order to maintain the quality. However, there is also a need for reduced lead-time and cost. Simulation can be a tool to achieve this. It can give information about dimension, shape, and residual stresses after each manufacturing process. LÄS MER

  3. 23. Self-bonding of beech veneers

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Carmen Cristescu; Luleå tekniska universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : This thesis presents studies on the self-bonding of veneers, and investigations into the properties of boards obtained by hot-pressing beech veneers without adhesives. The raw material is pressed at temperatures from 200 to 250ºC, at pressures from 4 to 6 MPa and pressing times from 240 to 360 s. LÄS MER

  4. 24. Investigation of the most essential factors influencing ski glide

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Leonid Kuzmin; Luleå tekniska universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wax; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : There are many different parameters of a ski running surface (material, roughness, hydrophobicity, etc.). All the parameters have an influence on ski glide, some more and some less. Furthermore, some parameters with only minor relevance are commonly declared as critical, while truly critical parameters, as far as we know, never been investigated. LÄS MER

  5. 25. Failure of vascular tissue with applications to the aneurysm wall, carotid plaque and myocardial tissue

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Caroline Forsell; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Cardiovascular disease is the leading cause of death in the modern world. Examples are thoracic aortic aneurysm (TAA), abdominal aortic aneurysm (AAA) and stroke due to plaque rupture. Failure in soft tissues caused by medical devices is also a medical challenge. LÄS MER
