Optimal Placement and Active Vibration Control of Composite Plates Integrated Piezoelectric Sensor/Actuator Pairs

Abstract: Abstract. This paper develops a finite element model based on first-order shear deformation theory for optimal placement and active vibration control of laminated composite plates with bonded distributed piezoelectric sensor/actuator pairs. The nine-node isoparametric rectangular element with five degrees of freedom for the mechanical displacements, and two electrical degrees of freedom is used. Genetic algorithm (GA) is applied to maximize the fundamental natural frequencies of plates and the constants feedba… Show more

“…A novel three-axis active mount using piezoelectric actuators is proposed and its effectiveness is verified through a vibration system subjected to vertical, rolling and pitching motions 20 Vibration control is achieved by quantifying the interaction between two active structural paths for source mass motion. Simulations and experiments show that multi-level vibration isolation can be achieved 21 .…”

“…Some researchers used singular value decomposition to obtain the objective function (Chhabra et al, 2016; Nadi et al, 2021). Tham et al (2018) established a finite element model based on the first-order shear deformation theory, took the maximization of the natural frequency obtained from the model as the objective function, and optimized it with genetic algorithm. Nor et al (2013) took minimizing the energy as the objective function to obtain the best location of the actuator and sensor, and recommended that the actuator and sensor be placed in the second-best location outside the interference area.…”
