  1. 1. Simulation of Wheel and Rail Profile Evolution : Wear Modelling and Validation

    Författare :Roger Enblom; KTH; []
    Nyckelord :contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Numerical procedures for reliable wheel and rail wearprediction are rare. Recent development of simulationtechniques and computer power together with tribologicalknowledge do however suggest computer aided wear prediction. LÄS MER

  4. 3. Simulation of contact, friction and wear in gears : a finite element approach

    Författare :Olle Lundvall; Linköpings universitet; []
    Nyckelord :Gears; Gear noise; Contact mechanics; Simulation; Friction; Wear; Transmission error;

    Sammanfattning : In this thesis, resent methods in computational contact mechanics is brought into the process of gear design. The finite element method is used to model two elastic bodies in contact. By defining a contact interface between these two bodies, constitutive laws, regarding normal contact, friction and wear, are included. LÄS MER

  5. 4. Modeling and Simulation of Physical Systems in a Mechatronic Context

    Sammanfattning : This thesis gives different views on the modeling and simulation of physical systems, especially together with embedded systems, forming mechatronic systems. The main considered application domain is automotive. LÄS MER

  7. 5. Modeling and Simulation of a Multi Phase Semi-batch Reactor

    Författare :Anna Nyström; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; semi-batch reactor; modeling; simulation; optimization; simulation;

    Sammanfattning : The operation of an industrial semi-batch reactor is modeled and the flow of one reactant is investigated. In the reactor a strongly exothermic polymerization reaction takes place followed by a slightly exothermic reaction, and the objective is to minimize the duration of the operation of the process.
