Passive vibration controllers with zero dynamic reaction

Recent progress in material processing and manufacturing have motivated increased interest of the scientific community in material optimization. Tailoring material properties to achieve the optimal response to a given solicitation provides an important input to the new materials development. This paper is focused on material model identification and posterior optimization of its material parameters in order to achieve zero dynamic reaction (zero transmissibility) in passive vibration one-dimensional controllers. Material models that allow for zero dynamic reaction are identified by analytical evaluation of transmissibility. Then parameters characterizing non-linear behaviour of selected components of the chosen material model are optimized by generic probabilistic metaheuristic algorithm simulated annealing. The optimization procedure is programmed within MATLAB environment. It is concluded that optimized designs have no distinguished feature and moreover the corresponding reaction suffer from high reaction peak in the initial transient region. Therefore optimization is extended to the transient region as well. Then plateau at the equilibrium force level is clearly identifiable.
