Structural-acoustic optimization of sandwich structures with cellular cores for minimum sound radiation

An optimization study of sandwich structures with cellular cores for minimum noise radiation in a wide frequency band, subject to the constraints on the fundamental frequency and weight is presented. Sensitivity functions of the radiated acoustic power are used to improve the computational time and...

Summary:An optimization study of sandwich structures with cellular cores for minimum noise radiation in a wide frequency band, subject to the constraints on the fundamental frequency and weight is presented. Sensitivity functions of the radiated acoustic power are used to improve the computational time and accuracy in near optimization. Numerical examples indicate that significant reduction of narrowband and broadband sound radiation can be achieved.
