  2. 1. Hydrodynamics and Complete Suspension in Axially Stirred Vessels

    Author : Claes Sturesson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; axially stirred tank; particle force balances; complete suspension; turbulence modeling; turbulent boundary layer; LDA;

    Abstract : Complete suspension of solid particles in stirred vessels has been subject to numerous investigationsin order to develop appropriate design criteria for solid/liquid suspensions. Previous work on this matter has often suffered from the lack of knowledge of fluid mechanics in the system and models based on overall flow characteristics have been proposed in the literature.

  5. 3. A Vibro-Acoustic Study of Vehicle Suspension Systems : Experimental and Mathematical Component Approaches

    Author : Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Henry Rice; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Vehicle suspension; Disc brake; Wheel rim Roughness noise; Interior tyre-road noise Component mode synthesis; Undeformed coupling interface;

    Abstract : The objective of the present work is to study the vehicle suspension as a vibro-acoustic system of high complexity, consisting of many sub-systems with fundamentally different acoustical properties. In a parallel numerical and experimental modelling effort, important contributions to the understanding of its behaviour have been achieved. READ MORE

  6. 4. Multi-objective optimization of railway bogie suspension damping

    Author : Albin Johnsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway vehicle dynamics; Bogie suspension design; Multi-objective optimization; Pareto optimized bogie primary and secondary suspensions damping;

    Abstract : In this thesis multi-objective optimization is used to find Pareto fronts showing the set of optimized damping parameters of primary and secondary bogie suspensions. Special interests are put on requirements to enhance safety and comfort of a railway vehicle. READ MORE

  7. 5. Vehicle Disc Brake Roughness Noise : Experimental Study of the Interior Noise andVibro-Acoustic Modelling of Suspension Systems

    Author : Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Wolfgang Kropp; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; disc brake; surface topography; wire brush noise; roughness noise; component mode synthesis; vehicle suspension;

    Abstract : Prediction of vehicle disc brake roughness noise is a non-trivial challenge. In fact, neither the source mechanisms, nor the transfer paths are so far well understood. READ MORE
