Sound Absorbency and Insulation Prediction of Multilayer Porous Materials by Set-Based Design Method

Abstract

A multilayer sound absorption/insulator including porous material is difficult to predict performance because of a number of design parameters such as Biot parameters and production tolerance. We developed a performance prediction system based on set-based design method that can obtain a ranged set of design solutions that satisfies sets of performance requirements through set-to-set space mapping from design space to performance space and space narrowing to eliminate infeasible design subspaces. Moreover, our system is applied to sound absorbency and insulation prediction.
