    Sammanfattning : The complexity of electronic systems in vehicles is rapidly increasing, and as a consequence, the long-term reliability of automotive connectors has become an important issue. The aims of this thesis have been: 1. to characterize the friction, wear and electrical properties of tin coatings, 2. LÄS MER

  4. 3. New insights into lubricated tribological contacts

    Författare :Elin Larsson; Staffan Jacobson; Åsa Kassman Rudolphi; Jannica Heinrichs; Philip Shipway; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; friction; wear; lubrication; fuel additive; boric acid; tribofilm; transport; fuel efficiency; surface analysis; grease; LiX grease; PP grease; fretting; electrical contacts; cross section; copper; silver; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : The emissions of carbon dioxide, CO2, must rapidly be reduced to avoid severe climate change. Tribology-related solutions can be an important part in reducing these emissions. The aim of this thesis is to improve the fundamental knowledge in two tribology-related fields, both concerning lubrication, to enable such solutions in the future. LÄS MER

  5. 4. Some Aspects of Wear and Structural Dynamics

    Författare :Jakob Knudsen; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Mechanical engineering; hydraulics; chaos; interfacial breakdown; stability; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; vacuum technology; fretting wear; fretting map; vibro-impact dynamics;

    Sammanfattning : The topic of this thesis is dynamics and wear of structures. In the six appended papers different aspects of wear and dynamics of a model system are studied. The considered system consists of a long slender rod with unilateral supports, subject to harmonic and stochastic excitation. LÄS MER
