The research presents a current-carrying plate coupled vibration of fluid fluctuation suppression principle, develops a kind of structural vibration fluid filter, uses the damped balance hole, static pressure balanced cavity and fluid pulsating energy of plate vibration attenuation, which achieves the common filtering of fluid resonance and structure resonance. By small disturbance theory, it conducts a dynamic analysis of the current-carrying plate under fluid coupling, discusses the dynamic characteristics of the attenuator with lumped parameter method, and sets up the transfer matrix mode, obtaining the first three resonance frequencies through simulation analysis that is consistent with the theoretical calculation. At last, it tests the performance of the experimental prototype, and proves that the attenuator has good fluid fluctuation attenuation effect at the coupling resonant frequency through analyzing the time domain of fluid pressure and the frequency domain signal, which also has certain inhibitor effectiveness for fluid system’s pressure fluctuation within its filtering bandwidth, verifying the correctness of the theoretical analysis and providing the new method to restrain the fluid system’s pressure fluctuation.
