This book was released on 2018-05-31 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research results contained in this technical report were performed under the NASA grant entitled "Experimental and Numerical Structural Acoustic Control for Interior Noise Reduction". The report is based essentially on partial progress of the Ph.D. dissertation prepared by Jeffrey S. Bevan under direct guidance of Dr. Chuh Mei. The document presents a finite element formulation and control of sound radiated from cylindrical panels embedded with piezoceramic actuators. The extended MIN6 shallow shell element is fully electrical-structural coupled. A piezoelectric modal actuator participation (PMAP) is defined which indicates the actuator performance to each of the offending modes. Genetic algorithm is also employed to validate the sensor and actuator locations determined by the PMAP criteria. The work was conducted at the Department of Aerospace Engineering, Old Dominion University. Mr. Travis L. Turner, Structural Acoustics Branch, NASA Langley Research Center is the technical monitor.Mei, Chuh and Bevan, Jeffrey S.Langley Research CenterNUMERICAL ANALYSIS; EXPERIMENTATION; NOISE REDUCTION; ACOUSTICS; ACTUATORS; RESEARCH; FINITE ELEMENT METHOD; SHALLOW SHELLS; POSITION (LOCATION); PIEZOELECTRICITY; PIEZOELECTRIC CERAMICS; PANELS; NUMERICAL CONTROL; NOISE (SOUND); CYLINDRICAL BODIES
