  1. 1. Dynamic response reconstruction using passive components

    Author : Anders Johansson; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

    Abstract : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. READ MORE

  2. 2. Prediction of structural dynamic behaviour under uncertainties: With applications to automotive structures

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Mladen Gibanica; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor localisation; experimental design; noise and vibrations; structural dynamics; automotive industry; model updating; uncertainty quantification; substructuring;

    Abstract : The automotive industry is moving towards shorter development cycles for new car generations. This means that less expensive prototypes can be built and tested, and that, increasingly, computer models must be used for decision making. READ MORE

  3. 3. Vibration transmission in lightweight buildings : Numerical prediction models

    University dissertation from Structural Mechanics, Lund University

    Author : Ola Flodén; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2016-12-22]

    Abstract : Ljud från grannar är ett återkommande problem för boende i flerfamiljshus. Problemen är generellt mer omfattande för de som bor i flervåningshus byggda i trä, en byggnadstyp som blir allt vanligare i Sverige. Många av de boende i trähus upplever även att störande vibrationer är vanligt förekommande i trähus. READ MORE

  4. 4. Machine Tool Dynamics - A constrained state-space substructuring approach

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Anders Liljerehn; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; State-space component synthesis; System identification; Receptance coupling; Chatter stability; Metal cutting; State-space models;

    Abstract : Metal cutting is today one of the leading forming processes in the manufacturing industry. The metal cutting industry houses several actors providing machine tools and cutting tools with a fierce competition as a consequence. Extensive efforts are made to improve the performance of both machine tools and cutting tools. READ MORE
