  2. 1. Dynamics of Vehicle-Deck Interactions

    Author : Junbo Jia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle-deck interactions; Lightweight structure; Vehicle dynamics; Vibration analysis.; Lashing; Vehicle securing; Ship motions; Modal testing; Finite element analysis;

    Abstract : The work presented in this thesis concerns the modelling and analysis of vehicle-ship deck interactions. The physical modelling of vehicles is discussed together with the modelling of supporting structures/ship decks, and the interactions between vehicles and supporting structures. READ MORE

  4. 2. Attenuation of hand-held machine vibrations. Application of non-linear tuned vibration absorber

    Author : Hans Lindell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Impact machine; Hand-arm vibration; High frequency vibration; ATVA; Nonlinear tuned vibration absorber; White finger; HAVS; Transient vibration; Auto Tuned Vibration Absorber; Vibration dynamics; ISO 5349;

    Abstract : Vibration injury in the hand-arm system from vibrating hand-held machines is one of the most common occupational health injuries and causes severe and often chronic nerve and vascular injuries to the operator. The objective with this study is to contribute to reduce hand-arm vibration injuries, first by developing methods of redesigning machines that will lower their vibration level and second to study how high frequency vibrations (HFV) above 1250 Hz effect the finger tissue which are not included in the current standard for risk evaluation.
