Abstract
Vibrational absorber is one of the common approaches for vibration control in structures. In this article, optimization criteria for mechanical systems under arbitrary vibrations is presented based on a multi-purpose method whose objective function vector collects the efficiency of arbitrary reliability and indexes of structure costs. The criterion is different from conventional criteria and standards used to design structures subjected to arbitrary vibrations and is based on minimizing the changes in displacement or response acceleration of the main structure, regardless of the required function for the failure. In this study, multi-purpose optimization approach to the design of vibrational an absorber is investigated to control non-uniform structural vibrations stimulating mechanical a mechanical structure based on an arbitrary acceleration process. It is performed based on bee optimization algorithm. In the following, a numerical example is shown for a simple vibrational absorber by this way. It shows the results of cost increase for decreased possibility of deconstruction, and therefore, allows appropriate decision making and selection based on need and cost.
