Abstract: | Structural dynamic modification techniques attempt to reduce dynamic design time and can be implemented beginning with spatial
models of structures, dynamic test data or updated models. The models assumed in this discussion are mathematical models,
namely mass, stiffness, and damping matrices of the equations of motion of a structure. These models are identified/ extracted
from dynamic test data viz. frequency response functions (FRFs). Alternatively these models could have been obtained by adjusting
or updating the finite element model of the structure in the light of the test data. The methods of structural modification
for getting desired dynamic characteristics by using modifiers namely mass, beams and tuned absorbers are discussed. |
