  1. 1. Accelerated granular matter simulation

    Författare :Da Wang; Martin Servin; Jin Ooi; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; discrete element method; nonsmooth contact dynamics; multibody dynamics; granular media; simulation; projected Gauss-Seidel; validation; iron ore pellets; pelletising balling circuit; model reduction; design optimization;

    Sammanfattning : Modeling and simulation of granular matter has important applications in both natural science and industry. One widely used method is the discrete element method (DEM). It can be used for simulating granular matter in the gaseous, liquid as well as solid regime whereas alternative methods are in general applicable to only one. LÄS MER

  3. 2. Multibody dynamic simulation in product development

    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

  5. 4. Contributions to the Modeling and Simulation of Mechanical Systems with Detailed Contact Analyses

    Författare :Iakov Nakhimovski; Dag Fritzson; Peter Fritzson; Claus Führer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multibody dynamics simulation; contacts; flexibility; elastic; floating reference frame; hybrid parallel; co-simulation; TLM; Computer science; Datavetenskap;

    Sammanfattning : The motivation for this thesis was the need for further development of multibody dynamics simulation packages focused on detailed contact analysis. The thesis makes contributions in three different areas:Part I summarizes the equations, algorithms and design decisions necessary for dynamics simulation of flexible bodies with moving contacts.

  7. 5. Simulation of Dynamic Interaction between Train and Turnout

    Författare :Elias Kassa; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic train–turnout interaction; wheel–rail contact geometry; switches and crossings; multibody dynamics; contact forces;

    Sammanfattning : Dynamic train–track interaction is more complex in railway turnouts (switches & crossings) than on ordinary tangent or curved tracks. Multiple contacts between wheel and rail are common, and severe impact loads with broad frequency contents are induced when the nominal wheel–rail contact conditions are disturbed due to the continuous variation in rail profiles and the discontinuities in the crossing panel.
