  1. 1. On the stability and control of piecewise-smooth dynamical systems with impacts and friction

    Detta är en avhandling från Stockholm : KTH

    Författare :Fredrik Svahn; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-smooth dynamics; nonlinear control; low-velocity impacts; friction; bifurcations; TECHNOLOGY Engineering mechanics Solid mechanics; TEKNIKVETENSKAP Teknisk mekanik Fastkroppsmekanik;

    Sammanfattning : This thesis concerns the analysis of dynamical systems suitable to be modelled by piecewise-smooth differential equations. In such systems the continuous-in-time dynamics is interrupted by discrete-in-time jumps in the state or governing equations of motion. LÄS MER

  3. 3. Microengineered CVD Diamond Surfaces Tribology and Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Joakim Andersson; Uppsala universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Diamond; DLC; Tribology; Friction; Environment; Microengineering; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Sammanfattning : Recent developments in thin film synthesis of diamond have facilitated a host of new technical applications. These are motivated by the many attractive properties of diamond, for example high hardness, chemical inertness, transparency and heat conductivity. Unfortunately, these properties also make it difficult to fashion complex geometries. LÄS MER

  4. 4. Synthesis, Characterization, and Evaluation of Ag-based Electrical Contact Materials

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Fang Mao; Uppsala universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrical contact; bulk; coating; Ag-based alloys; Ag-based delafossite; AgI; graphene; graphene oxide; combinatorial material science; dc magnetron sputtering; friction; wear; hardness; contact resistance;

    Sammanfattning : Ag is a widely used electrical contact material due to its excellent electrical properties. The problems with Ag are that it is soft and has poor tribological properties (high friction and wear in Ag/Ag sliding contacts). LÄS MER

  5. 5. On the influence of surface roughness on rolling contact forces

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Oskar Lundberg; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rolling contact; Surface roughness; Contact forces; Contact modelling; Friction; Road; Asphalt; Substrate; Test-rig; Sliding; Stick–slip; Tyre; Rubber; Tread-block; Wheel–rail interaction; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Road vehicle tyres, railway wheels and ball bearings all generate rolling contact forces which are transferred within a finite area of contact between the rolling element and the substrate. Either it is visible or not for the human eye, a certain degree of roughness is always present on the contacting surfaces and it influences the generation of both vertical and lateral contactforces.
