| description | This paper presents optimization of vibration damping for a rectangular thin plate using a single
piezoelectric (PZT) patch shunted with negative capacitance, by utilizing the ant colony optimization (ACO)
algorithm. The frequency range to be controlled is presented in the context of statistical energy analysis (SEA) where
modal overlap factor (MOF) is considered i.e. MOF<1 (low), 1<MOF<2 (mid) and MOF>2 (high). The effects of
two different shunt circuits on the system are studied; series and parallel resistor-negative capacitor (R-C). The
governing equation of motion for a PZT patch shunt attached on a thin plate is obtained using Lagrange’s equation,
and ACO algorithm is utilized to obtain the optimum spatial coordinate of the PZT patch and resistor values of the
shunt circuit for the different frequency regions, targeting for maximum energy reduction of the vibrating thin plate. |
