Forming accurate dynamic models through finite element (FE) methods always requires the system parameters to be precise. Given that a few frequency response functions (FRFs) of a dynamic system have been measured, an efficient FRF-based FE model updating method is developed to simultaneously update the system’s stiffness, damping and mass parameters. Instead of using the measured FRFs directly for model updating, the proposed method develops an efficient scheme to first extract the poles and zeros associated with a measured FRF, then derives a cross-model cross-mode-based (CMCM-based) updating method that utilized both measured poles and zeros. Two numerical examples, including computer simulation and lab experiment, are provided to demonstrate the excellent performance of the proposed method.
