摘要:
为了有效地激励出圆环板的面外振动模态，提出用4个兰杰文振子的纵振作为激励源的方式。介绍了激励源的布置方式，并对圆环板进行了有限元模态分析和结构尺寸的参数分析。制作了原理样机，采用多普勒激光测振仪对样机进行了模态实验，测试结果与有限元分析结果比较吻合。当施加电压峰峰值为150 V时，振幅为700 nm左右；当施加的激励电压峰峰值达到200 V时，振幅达到900 nm以上。实验表明，用4个兰杰文振子的纵振可以有效地激励出圆环的面外振动模态，合理地控制两相所加电压的相位差可以形成行波。
Abstract:
To excite the vibration modal out-plane of the ring plate, the longitudinal vibration of four Langevin vibrators serve as the excitation source. The paper presents the excitation arrangement and conducts a finite element modal analysis and structural and dimensional parameter analysis for the ring plate. A prototype is fabricated and subject to a modal experiment with the laser Doppler vibration meter. The testing result coincides with the finite element analysis. The amplitude is about 700 nm, at a peak voltage of 150 V and the amplitude can be over 900 nm at a peak voltage 150 V. Experiments show that the longitudinal vibration of four Langevin vibrators can effectively excite the vibration modal out-plane of the ring plate and rational control of the phase difference between the applied voltages can create traveling wave.
