  1. 1. Design, testing and analysis of journal bearings for construction equipment

    Författare :Henrik Strand; Sören Andersson; Arto Lehtovaara; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact Mechanics; Finite Element; Grease; Journal Bearing; Lubrication; Replica Technique; Test Apparatus; Tribology; Wear; Mechanical manufacturing engineering; Mekanisk tillverkningsteknik;

    Sammanfattning : Grease-lubricated journal bearings present a common challenge for construction equipment manufacturers in the world. The common design methodology is based on empirical data and has worked very well historically because the market and governments have accepted that bearings in construction equipment need frequent lubrication and exchange of worn parts.

  3. 3. Confined Compression of Single Particles : Development of a Novel Triaxial Testing Instrument and Particle-Scale Modelling

    Författare :Henrik Jonsson; Göran Frenning; Göran Alderborn; Abderrahim Michrafy; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Powder compaction; Compression; Single particle; Particle mechanics; Powder mechanics; Confined conditions; Triaxial; Apparatus design; Modelling; Galenisk farmaci; Pharmaceutics;

    Sammanfattning : When predicting the performance of a powder compaction process, assessing the behaviour of the particles comprising the powder bed is of central relevance. Currently, however, no experimental methods are available for mimicking the multiaxial loading conditions imposed on the individual particles in a powder bed during compaction, and such analyses are therefore usually performed in silico.

  4. 4. Studies of high-temperature superconducting tapes and their application in power apparatus

    Författare :Torbjörn Wass; Sven Hörnfeldt; Runde Magne; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrocity physics; magnetism; electronics engineering; electrical engineering; Electrical engineering; Elektroteknik;

    Sammanfattning : Intensive development in the field of high-temperature superconductors (HTS) has resulted in long length HTS with high current carrying capacity. The performance of HTS in the form of multifilamentary silver sheathed Bi-2223 tapes is close to the requirements for power application. LÄS MER

  5. 5. The safety relevance of standardized tests for diving equipment

    Författare :Mårten Silvanius; Oskar Frånberg; Greg Murphy; Blekinge Tekniska Högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; rebreather; underwater breathing apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring;

    Sammanfattning : Vital components are more or less prone to fail in a diving apparatus. This thesis examines the performance of oxygen sensors, carbon dioxide scrubber monitoring and composite gas cylinders. LÄS MER
