  1. 31. CE-märkning av produkter under byggproduktförordningen

    M1-uppsats, Institutionen för maskinteknik (MT)

    Författare :Martin Jidegren; David Sannéus; [2013]
    Nyckelord :Brackets; CE-marking; Construction products regulation; ETAG 015; Manufacturing control; Nailing plates; Standard; Byggproduktförordningen; CE-märkning; ETAG 015; Spikplåtar; Standard; Tillverkningskontroll; Vinkelbeslag;

    Sammanfattning : The purpose of this study is to achieve an understanding of how a CE- marking process is conducted and to identify the relevant factors that must be considered in such a process. We have conducted our study at Lövhults Svets & Smide AB (Lövhults) in Skruv, Småland Sweden, which are manufacturing brackets for small covering constructions. LÄS MER

  3. 32. Optimering av sintrade kugghjul

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Mario Sosa; [2012]
    Nyckelord :;

    Sammanfattning : Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. LÄS MER

  4. 33. Analysis and vibration improvements of a forwarder seat

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Xuan Sun; [2012]
    Nyckelord :;

    Sammanfattning : I skogsbruket är både förare och fordon utsatta för höga vibrationsnivåer. Stolen i dagens skotare är en av de viktigaste delarna för att kunna isolera föraren från helkroppsvibrationer (WBV). Idag är de flesta stolarna tillverkade utifrån lastbilskrav. LÄS MER

  5. 34. Utilizing statistical process control analysis and EPID for routine QA of medical linear accelerators

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Patrik Andersson; [2011]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose: The main purposes of this study is to a) evaluate the suitability of a Varian aS1000 EPID as a safe quality assurance device for control of machine specific parameters, such as linac output, beam quality and beam symmetry, and b) to investigate the usefulness of the SPC concept for evaluation of the obtained data. Method and Materials: Measurements were performed using a Varian Clinac 2300iX linear accelerator (Varian, Inc. LÄS MER

  7. 35. Development of a pre-knitting friction test method and study of friction and bending of yarns with high stiffness.

    Magister-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :Joel Peterson; Ellinor Vegborn; [2009]
    Nyckelord :knitting technology; carbon fibres; pet fibres; aramid fibres; flexural rigidity; friction;

    Sammanfattning : Knitting is a class of techniques for production of textile fabrics by inter-looping yarns withthe use of hooked needles. The new loops are created when the yarns drawn through thepreviously formed loops. LÄS MER
