Abstract
To realize metal foil consolidation, a push–pull high-power ultrasonic consolidation resonance system is designed. Firstly, the structure of a high-power piezoelectric transducer was designed and calculated, the push–pull ultrasonic consolidation resonance system was designed according to requirements of ultrasonic consolidation. Secondly, the finite element modal analysis of the ultrasonic consolidation resonance system was carried out, the natural frequency and vibration mode were obtained. The dynamic simulation of the ultrasonic consolidation resonance system was carried out based on the four-terminal network method and MATLAB/Simulink, the displacement of piezoelectric transducer and the resonance system was obtained, the output displacement of piezoelectric transducer and the consolidation sonotrode end surface is 6 μm and 20 μm respectively. Thirdly, the dynamic model of the consolidation resonance system was established, according to the transfer function, the root locus method and frequency response method were used to analyze the characteristics of the system. Finally, the sweep frequency and impedance measurement of piezoelectric transducer were carried out, and the sweep frequency and fixed frequency measurement of the ultrasonic consolidation resonance system were also carried out. Experimental results show that the resonant frequency of piezoelectric transducer is 19,875 Hz, and the minimum impedance value is 261.43 $$\Omega$$ when the frequency is near 20 kHz. When applying 120 V and 160 V voltage signal, the resonant frequency is 20,039 Hz and 20,055 Hz, the maximum displacement of the sonotrode which is excited by double piezoelectric transducers is about 16 μm. The ultrasonic consolidation machine is fabricated, which can meet requirements of metal foil consolidation, such as high-power and amplitude.
