RISVibration Confinement via Optimal Eigenvector Assignment and Piezoelectric Networks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The underlying principle for vibration confinement is to alter the structural vibration modes so that the corresponding modal components have much smaller amplitude in concerned area than in the ...
An Active-Passive Piezoelectric Absorber for Structural Vibration Control Under Harmonic Excitations With Time-Varying Frequency, Part 1: Algorithm Development and Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has been shown that piezoelectric materials can be used as passive electromechanical vibration absorbers by shunting them with electrical networks. Semi-active piezoelectric absorbers have also ...
An Active-Passive Piezoelectric Absorber for Structural Vibration Control Under Harmonic Excitations With Time-Varying Frequency, Part 2: Experimental Validation and Parametric Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Part 1 of the paper, a new high-performance active-passive hybrid piezoelectric absorber concept was presented. This design is an attractive alternative to semi-active absorbers for the purpose ...
