摘要

将压电喷墨打印头作动器作为矩形层合板进行振动分析。利用压电板理论和瑞利-里兹法，建立了矩形层合压电薄板的解析模型，推导并求解了薄板受迫振动的控制方程。对矩形板的主共振进行了变形和频率分析。得到了系统的幅频响应曲线和一阶振型。研究结果可用于改进电驱动喷头结构。

Vibration Analysis of Laminated Plates in a Piezoelectric Inkjet Printhead

The actuator of piezoelectric inkjet printhead is analyzed as a rectangular laminated plate for vibrations. With the theory of piezoelectric plates and Rayleigh-Ritz method, an analytical model of laminated piezoelectric rectangular plate was established, and the governing equations were derived and solved for forced vibrations of the thin-plate. The primary resonance of rectangular plate is investigated for the deformation and frequency. The amplitude-frequency response curve and the first-order vibration mode shapes are obtained. The results in the present study is to be used for the improvement of electric driving of printhead structure.
