Optimization of dynamic vibration absorbers over a frequency band

Abstract

A methodology for the optimum design of single and multiple dynamic vibration absorbers, applicable to multi-degree-of-freedom damped primary systems, is proposed. The method is based on a substructure coupling technique that can be used to explore analytical or experimental frequency response functions. The problem is formulated as a general nonlinear optimization problem for which different types of design constraints can be considered. Since only a small number of coordinate points are concerned in the substructure coupling method, only small matrices have to be manipulated. Consequently, the method is very computationally efficient.
