  2. 21. Accelerated granular matter simulation

    Author : Da Wang; Martin Servin; Jin Ooi; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 22. Wavelet Galerkin methods for elastic multibody systems with unilateral contact constraints

    Author : José Díaz López; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Elastic MBS; Contact; Unilateral Contraints; Wavelet; DAE; Daubechies; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

    Abstract : In this thesis we investigate the applicability of wavelets to simulate the time behavior of elastic multibody systems (MBS) with contact constraints. For this end, a wavelet element method (WEM) was implemented, exploiting the special structure of the coupled ODE/PDE equations that govern elastic MBS. READ MORE

  5. 23. Contributions to Modelling and Visualisation of Multibody Systems Simulations with Detailed Contact Analysis

    Author : Alexander Siemers; Dag Fritzson; Peter Fritzson; Mats G. Larson; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The steadily increasing performance of modern computer systems is having a large influence on simulation technologies. It enables increasingly detailed simulations of larger and more comprehensive simulation models. Increasingly large amounts of numerical data are produced by these simulations. READ MORE

  6. 24. Dynamic Vehicle-Track Interaction of European Standard Freight Wagons with Link Suspension

    Author : Per-Anders Jönsson; Sebastian Stichel; Evert Andersson; Jerzy Piotrowski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; freight wagon; running gear; link suspension; laboratory test; ; stiffness; dry friction; hysteresis; simulation; vehicle-track interaction; multibody; simulation; MBS; Vehicle engineering; Farkostteknik;

    Abstract : The link suspension is the most prevailing suspension system for freight wagons in Central and Western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. READ MORE

  7. 25. Contributions to the Modeling and Simulation of Mechanical Systems with Detailed Contact Analyses

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

    Abstract : 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.
