    Sammanfattning : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and product quality. Other reasons for using industrial robots are cost saving, and elimination of hazardous and unpleasant work. LÄS MER

  3. 2. Carbody and Passengers in Rail Vehicle Dynamics

    Författare :Pelle Carlbom; KTH; []
    Nyckelord :Rail-Vehicle Dynamics; Human-Body Dynamics; Ride Comfort; Structural Dynamics;

    Sammanfattning : The carbody plays an important role in rail vehicle dynamics.This thesis aims atdeveloping validated modelling methods tostudy its dynamics, how it is excited on trackand how itinteracts with the passengers. The primary interest is ridecomfort,considering vibrations up to 20 Hz. LÄS MER

  4. 3. Modelling and Simulation of Train-Track Interaction including Wear Prediction

    Författare :Clas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale measurements; rail corrugation; substructuring; wheel-rail contact; multibody dynamics; dynamic train-track interaction; three-dimensional motion;

    Sammanfattning : Many problems in railway traffic arise as a result of the dynamic interaction between rolling trains and tracks. The problems include both instantaneous effects due to induced vibrations of track and vehicle, and more long-term processes of a detrimental nature. 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.
