  1. 1. Cam Roller Contact : The topographical aspect

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Frédéric Cabanettes; Högskolan i Halmstad.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics Mechanical manufacturing engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk tillverkningsteknik; injection cam; roller; surface topography; rough contact model; wear test; classification of surfaces; manufacturing evaluation;

    Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. First order aspects defining the main functions of a component are well known and new challenges appear at a lower scale. LÄS MER

    Sammanfattning : A time-discrete formulation of the variational principle of mechanics is used to provide a consistent theoretical framework for the construction and analysis of low order integration methods. These are applied to mechanical systems subject to mixed constraints and dry frictional contacts and impacts---machines. LÄS MER

  3. 3. Finite Element Modeling of Contact Problems

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Asim Rashid; Linköpings universitet.; Linköpings universitet.; [2016]

    Sammanfattning : Contact is the principal way load is transferred to a body. The study of stresses and deformations arising due to contact interaction of solid bodies is thus of paramount importance in many engineering applications. In this work, problems involving contact interactions are investigated using finite element modeling. LÄS MER
