Abstract:Modal control algorithm and optimal sensor placement for an electrorheological sandwich plate under semiactive variable modality stiffness vibration control were investigated. First of all, on the modal coordinate, a modal coordinate estimation method was obtained according to the demand of the control algorithm. And then, an optimal model was developed based on the analysis of vibration mode shape. Lastly, complete enumeration was adopted after filtering the structure nodes and these optimal configurations were verified by two kinds of comparisons of precision in calculation and vibration control. The numerical example shows that this modal coordinate estimation from the configuration with a few sensors can satisfy the demands of modal control algorithm. © 2017, Editorial Office of Journal of Vibration and Shock.
