Abstract

Recently, an adaptive structure concept based on fluidic flexible matrix composite (F²MC) cells has been investigated for its potential to provide multiple functionalities simultaneously. This structure consists of different F²MC cells that are connected through internal fluidic circuit, and due to the interaction between the fluid flow and cell wall deformation, the structure exhibits distinct system poles and zeros. By adjusting the F²MC cellular design parameters, the poles and zeros can be placed at appropriate positions so that the cellular structure can perform dynamic functions such as vibration absorption and dynamic actuation. In order to fully explore the potential of the F²MC based cellular structure, this research develops a synthesis procedure for a triple cellular structure based on a set of prescribed poles and zeros. This procedure is essentially a hybrid numerical method combining the Jacobi inverse eigenvalue problem solver and genetic algorithm with discrete variables. It is capable of selecting physically feasible design parameters for each F²MC cell in order to achieve the desired pole and zero positions accurately.
