  1. 1. Influence of the Non-linear Effects in the Design of Viscous Dampers for Bridge Cables

    Master-uppsats, KTH/Byggvetenskap; KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Författare :Yalda Acar; Pontus Jingstål; [2014]
    Nyckelord :Bridge cables; external viscous damper; half-power bandwidth method; loss factor; non-linear vibration; Brokabel; externa viskösa dämpare; half-power bandwidt metoden; förlustfaktor; icke-linjär vibrationer;

    Sammanfattning : In this master thesis the performance of external viscous dampers attached to cables in cable-stayed bridges have been studied. A comparison has been performed between a linear and a non-linear cable model. The comparison was carried out for two bridge cables, one from the Dubrovnik Bridge and the other from the Normandie Bridge. LÄS MER

  3. 3. A measurement method for damping of drive shaft

    H-uppsats, Chalmers tekniska högskola / Institutionen för teknisk akustik; Chalmers University of Technology / Department of Applied Acoustics

    Författare :Anders Bertilsson; [2004]
    Nyckelord :Samhällsbyggnadsteknik; Civil Engineering;

    Sammanfattning : Sound in our society is beginning to be a health hazard in many places. This leads to legislation and recommendations by public authorities and governments. For a truck the sound pressure level should not exceed 80 dB(A) during a drive-by test set by international standards. LÄS MER
