Abstract


In this study, frequency separation maximization and radiation acoustic power minimization of the laminated plate are simultaneously considered based on genetic algorithm. A double-objective genetic algorithm is used to obtain Pareto-optimal designs for frequency separation maximization and radiation acoustic power minimization. A four-layer laminated plate is used as an example, and the numerical simulations show that different weight coefficient ratios are chosen, Pareto optimal solution of double objective of the laminated plate are obtained.
