4. 2. Electrical and Frictional Performance of Tin-Coated Contacts Exposed to Wear and Fretting Corrosion

   Author : Tag Hammam; Åke Öberg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Friction; Fretting; Wear; Contact resistance; Tin; Connectors; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : 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. READ MORE

5. 3. Some Aspects of Wear and Structural Dynamics

   Author : Jakob Knudsen; Hållfasthetslära; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. New insights into lubricated tribological contacts

   Author : Elin Larsson; Staffan Jacobson; Åsa Kassman Rudolphi; Jannica Heinrichs; Philip Shipway; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 5. Vibro-impact dynamics of fretting wear

   Author : Jakob Knudsen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Abstract : The dynamics and wear of non-linear impact oscillators, comprising a single-degree of freedom system as well as continuous beam systems are analysed. The considered beams are of cantilever type with the lateral motion of the free end constrained by elastic supports. They are modelled as Bernoulli beams with Rayleigh damping. READ MORE
