Dynamic characterization of bolted joints using FRF decoupling and optimization
An experimental identification method is developed for structural joints. FRF decoupling method is used in the identification of joint stiffness and damping. The optimization algorithm improved the identified parameters significantly. Very good results are obtained for bolted beams. The method is found to be promising to be applied to more complex structures.
