Structural dynamic modification is a popular approach to obtain desire frequencies and dynamic characteristics.
It has been observed that reanalyzing the modified structure usually involves complicated calculations when modifications are concerned with numerous degrees of freedom (DOFs), especially adding substructures to these DOFs.
This paper proposed a method to reanalyze the frequency response functions (FRFs) of structures with multiple co-ordinates modifications.
Two different cases are taken into consideration in the modifications, including adding (or decreasing) masses, stiffness, and damping, as well as adding spring-mass substructures, which makes the method more practical.
This method is developed by employing Sherman–Morrison and Woodbury (SMW) formula based on the FRFs related to the modifications coordinates of the original system.
The advantage of this method is that neither a physical model nor a modal model is required; instead, it needs only the FRFs, which can be directly measured by experimental modal testing.
Another salient feature of this proposed strategy is that the FRFs of the modified structure can be calculated in only one step.
Validation of this proposed method is demonstrated using various numerical examples.
It is shown that the method is very effective and can be considered for real applications.
