N2 - In the paper the analysis of random vibration of an actively damped laminated plate with functionally graded piezoelectric actuator layers is presented. The simply supported plate is subjected to stochastic loading represented by a uniformly distributed pressure. The random input is assumed as a Gaussian sta- tionary and ergodic process. The actuators are regarded as a multi-layer structure arranged of piezofiber composite sub-layers. The sub-layers differ each other with amount of PZT (lead-zirconate-titanate) fibers and are stacked to achieve a desired change of the PZT volume fraction through the actuator thickness. The gradation scheme of constituents and material properties are estimated by parabolic and power functions. Numerical simulations are performed to recognize the influence of the applied random excita- tions and the actuator properties gradations on the characteristics of the stochastic field of active plate deflection i.e. power spectral density, autocorrelation function and variance L1 - http://www.czasopisma.pan.pl/Content/101372/PDF/12_paper.pdf L2 - http://www.czasopisma.pan.pl/Content/101372 PY - 2015 IS - No 1 EP - 108 DO - 10.1515/aoa-2015-0012 KW - laminated plate KW - piezoceramic control KW - functionally graded actuator KW - stochastic pressure A1 - Pietrzakowski, Marek PB - Polish Academy of Sciences, Institute of Fundamental Technological Research, Committee on Acoustics VL - vol. 40 DA - 2015[2015.01.01 AD - 2015.12.31 AD] T1 - An Active Functionally Graded Piezocomposite Plate Subjected to a Stochastic Pressure SP - 101 UR - http://www.czasopisma.pan.pl/dlibra/publication/edition/101372 T2 - Archives of Acoustics
