Active Vibration

Theoretical and finite element models of maglev actuator are both established. Magnetic conductive rubber is added into the actuator to improve its performance. Numerical simulations and experiments show that adding conductive rubber increases the output force-power ratio while reduces the dynamic response slightly.

Active Vibration

A finite element formulation for active vibration control of laminated composite plate integrated with active fiber composite (AFC) layer acting as distributed actuator and PVDF layer as sensor is presented in this paper. An eight noded quadratic isoparametric element with five mechanical degrees of freedom and one electrical degree of freedom per node of the element is considered. Newmark time integration method is used to calculate the dynamic response and negative velocity feedback control algorithm is used to control the dynamic response of the laminated composite plate. The effect of piezoelectric fiber orientation in actuator layer on the control of vibration is studied.

Active Vibration

In order to solve the active vibration control of piezoelectric smart structures, focus problems on the structural analysis of the dynamic characteristics. To piezoelectric smart structure for the research object, finite element modal analysis, solving the natural frequency and response characteristics. Firstly, analyzed the problems of structural eigenvalues ​​and eigenvectors problems, then prepared dynamic response analysis program of FEM based on MATLAB, and complete the theoretical model calculations. At the same time, using ANSYS software to simulate and analyze, theresults show that, ANSYS simulation result is consistent with the theoretical value, so as to study the piezoelectric active vibration control of smart structures and lay a good foundation.
