  3. 3. Mechanical dry grinding process of saw chain

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap; Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Dennis Svensson; Tobias Falk Svärd; [2019]
    Nyckelord :dry grinding; abrasive; grinding wheel; grinding disc; grinding wheel; friction; energy; work; chainsaw; saw chain; cutting link; cutting edge;

    Sammanfattning : The cutting links on chainsaws needs to be sharpened regularly to retain its sharpness. The most effective way is to use a machine wheel grinder. However, due to high friction there is a high risk of tempering the steel and damaging the sustainability to wear, resulting in a dull cutting edge. LÄS MER

  4. 4. Uses and Issues – The case of Visby Cathedral : An analysis of values and frictions associated with usage at a venue that is both cultural heritage and an active religious institution

    Magister-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Walter Duphorn; [2019]
    Nyckelord :;

    Sammanfattning : This thesis is a case study of Visby Cathedral, cultural heritage with a rich history that has been an active site of worship since medieval times. This has resulted in an interest in the cathedral as a tourist destination which has increased exponentially since the city became a world heritage. LÄS MER

  5. 5. Simulation and Analysis of Ultrasonic Wave Propagation in Pre-stressed Screws

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Erik Andrén; [2019]
    Nyckelord :;

    Sammanfattning : The use of ultrasound to measure preload in screws and bolts has been studied quite frequently the last decades. The technique is based on establishing a relationship between preload and change in time of flight (TOF) for an ultrasonic pulse propagating back and forth through a screw. LÄS MER
