Multi-Objective Optimization of Acoustic Sandwich Panels

In this paper the optimal acoustic design of sandwich panels is studied in a comprehensive way with an attempt to establish a methodology to assist the acoustic analysts and panel designers in making appropriate trade-offs between conflicting objectives. Closed-form relationships between design objectives and design variables are obtained for panel cost and for panel loading and deflection from various mechanics models of panel response. Four different objectives—Transmission Loss, Cost, Panel End-Loading, and Mid-Span Deflection—are combined to carry out the multi-objective optimization. Finally, ways for the selection of the best-compromise solution are indicated
