Abstract：Here, the aero-engine blade vibration suppression method based on piezoelectric shunt damping technique was studied. Firstly, for an electro-mechanical coupled system composed of blade structure and piezoelectric ceramics, its finite element dynamic model was established, and the model reduction was performed. Then, the principles of classical resonant shunt circuit and an inductor-resistor shunt circuit with negative capacitance were analyzed. Finally, a piezoelectric shunt damping circuit was constructed, and the physical realization method of large inductance and negative capacitance was studied in detail. Vibration suppression effect of piezoelectric shunt damping on compressor blade structure of a certain type aero-engine was examined with tests. The test results showed that the proposed method introduces a concept of “equivalent capacitance” for piezoelectric ceramics, and it can correctly predict dynamic characteristics of blade-piezoelectric ceramics electromechanical coupled system, and have a capability to deal with actual complex blade structure; resonant shunt circuit has a significant effect to suppress blade’s single order modal vibration; introduction of negative capacitance can effectively enhance piezoelectric shunt damping effect.
