Vibration Measurements on the Frejlev Mast

    Research output: Book/ReportReportResearch


    The present report presents full-scale measurements on the Frejlev-mast which is a 200 meter hight guyed steel mast located 10 km. from Aalborg. The goal of the research was to investigate various techniques which could be used to estimate cable forces from vibration measurements. The cables of the Frejlev mast were instrumented in order to measure strains in the cables. However, it was found that the strain signals had a too low signal to noise ratio to be used for further analysis. Since the strain signals could not be used some of the five cables became instrumented with accelerators of cables in three directions were measured three different types of excitation: wind, free-decays and harmonic excitation by shaking the cables by the hand.
