1. 16. On Contact Mechanisms and Mechanical Transmission Performance

   Författare :Lars Maclennan; Maskinelement; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; hydraulics; Mechanical engineering; artificial neural network; experimental study; disc brake; dynamic analysis; shaft; Spur gear;

   Sammanfattning : This thesis consists of four papers, which treat the modelling of a spur gear set and a disc brake, and the interaction between the machine elements. Features of the performance are studied in relation to the initial stated assumptions. LÄS MER

3. 17. 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

   Sammanfattning : Surfaces subjected to rolling and sliding contacts may suffer from contact fatigue. The cam and roller follower mechanism is a typical rolling and sliding contact. LÄS MER

5. 19. Effect of water contamination on the diffused content of hydrogen under stress in AISI-52100 bearing steel

   Författare :Tajammal Imran; Maskinelement; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; hydraulics; Mechanical engineering; materialteknik; Materiallära; Material technology; Hydrogen Diffusion; Rolling Element; Machine Elements; Tribology; Hydrogen Embrittlement; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Sammanfattning : Abstract Hydrogen embrittlement is a degradation process of mechanical/tribological properties (toughness, wear etc.) of mating steel surfaces. This is caused by the presence and interaction of hydrogen with applied stresses. Therefore, it is important to quantify the hydrogen content which could be dissolved under applied stresses in steel.

7. 20. Branch Identification in Elastic Stability Analysis

   Författare :Anders Magnusson; Hållfasthetslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; hydraulics; Mechanical engineering; Produktionsteknik; Production technology; FEM; computer simulation; bifurcation; stability; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Sammanfattning : In this thesis, methods to determine the static postbuckling behaviour of elastic structures undergoing large deformations, are considered and developed. Since the governing non-linear equations usually becomes too complex to be handled analytically, the main focus has been on developing methods that can be incorporated into a numerical solution scheme, such as the finite element method.
