N2 - This paper presents the dynamic characterization of a flexible matrix composite (FMC) driveshaft. A primary objective is to experimentally validate the analytic modelling of a FMC shaft based on the equivalent modulus beam theory (EMBT). A test rig is developed which consists of a FMC shaft, a foundation beam and bearings, a driving motor and a shaker. Then, experimental characterization of the FMC shaft is performed by measuring responses of both the FMC shaft and the foundation beam under the base excitation with a frequency sweep up to 130 Hz and imbalance loadings while spinning up the FMC shaft continuously near the 1st resonance. Results show that the measured responses around vertical shaft modes are observed in a fairly good correlation with the predicted from the EMBT modelling. Consequently, the shaft modelling based on EMBT can be utilized to estimate the dynamic behaviours of a FMC shaft. This is further validated by spin-up results, where a good agreement in the rate of response increase is observed between the measured and the predicted. Copyright
