Abstract
The invention discloses a method for sticking a piezoelectric ceramic actuator in structural vibration control. The method comprises the following steps of: 1) polishing and coursing the sticking area of a member surface on which the piezoelectric ceramic actuator is needed to be covered; 2) degreasing, cleaning and drying the cathode of the piezoelectric ceramic actuator and the sticking area ofthe member surface; 3) preparing silver powder conductive adhesive; and 4) placing the piezoelectric ceramic actuator with the cathode facing the external in a groove of a clamp, coating the conductive adhesive on the cathode of the piezoelectric ceramic actuator and the sticking area of the member, and buckling the cathode of the piezoelectric ceramic actuator facing the sticking area of the member on the sticking area of the member, and curing for 5 to 8 hours under the pressure of 0.4 to 0.6 kilograms / square centimeter and at the temperature of 40 to 60 DEG C. Compared with the common sticking method, the method has the advantages that: actuating efficiency of the piezoelectric ceramic actuator is improved effectively, the effect of inhibiting the controlled object is enhanced, the cathodes of all piezoelectric ceramic actuators are connected together through a metal structure, and the wiring number of the controlled object is reduced.
Description
technical field [0001] The method relates to a bonding method for enhancing the function of piezoelectric ceramic actuators in structural vibration control, and particularly relates to a bonding method of piezoelectric ceramic actuators on the surface of metal structures. Background technique [0002] With the maturity of piezoelectric technology, piezoelectric materials have been widely used, which promotes the current research on active vibration control of various structures. One of the active vibration control methods is to paste piezoelectric ceramic actuators on the surface of the controlled object, and use the piezoelectric effect to suppress the vibration of the controlled object. Chinese patent ZL 200810027186.4 (Space sailboard bending and torsional modal vibration simulation active control device and method) adopts this active vibration control method, but does not provide a method for pasting the piezoelectric ceramic actuator on the controlled object. The gener...
