Optimal Design of Piezoelectric Smart Structures for Achieving a Silent Zone in an Enclosure

초록

This paper presents a new methodology for designing smart structures in the sense of structure-borne noise. After deriving the governing equation of motion, pressure levels are analyzed by changing the location of the piezoelectric actuators. This is accomplished by employing inhousingly-developed optimal code. The acoustic levels are compared between initial and optimal designs and the effectiveness is demonstrated in the time domain.
