  1. 1. A Methodology for Efficient Conceptual Design Analysis of Nonlinear Dynamic Structural Systems

    Författare :Niclas S Andersson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; State-space models; Model order reduction; Conceptual design models; Flexible multibodies; Balanced truncation; Component Mode Synthesis; Nonlinear dynamics; Driveline systems;

    Sammanfattning : There is a typical requirement conflict between fuel consumption and noise and vibrations in passenger cars. Obviously the combustion engine is a major source of vibration and has an influence on vehicle emissions. Similar properties apply to the power transferring mechanical driveline system. LÄS MER

  2. 2. Characterisation of Nonlinear Structural Dynamic Systems in Conceptual Design

    Författare :Niclas S Andersson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Structural dynamics; Model order reduction; Nonlinear characterisation; Multi-body dynamics; Frequency response functions; Multisines; Response classification; Driveline systems; Concept design analysis; Stepped-sine; Support vector machine;

    Sammanfattning : The engine and driveline systems of passenger cars generates and distributes the necessary driving power and are major contributors to vehicle emissions, noise and vibrations, etc. More environmental friendly technologies under development are expected to intensify and add new comfort related problems, since most of them affect vibration sources or system damping.
