A Simultaneous Frequency Domain Technique for Estimation of Modal Parameters from Measured Data 811046

A new method for estimation of vibration mode parameters from measured frequency response functions is introduced. Response functions associated with selected “independent” degrees of freedom are employed simultaneously to deduce an effective dynamic matrix with a linear least-square technique. Vibration mode parameters are then deduced from the dynamic matrix. An additional least square relationship among “independent” and “dependent” degrees of freedom provides the means for estimation of mode shapes associated with all measurement locations.
