説明

Residual flexibility which represents the influence of vibration modes in higher frequency range, takes an important role in structural modification simulation for more accuracy. The paper describes how to determine these residual flexibilities based on measured frequency response functions after curve fitting process for modal parameter extraction. Further a new method is proposed to correct these residual flexibilities and applied to mathematical models and to actual structures in order to show the effectiveness.
