摘要: 现代化的自动装配对物料输送的平稳性和精确性提出了更高的要求,为了满足工业需求,设计了一种采用矩形压电振子作为激振源、以垂直驱动方式工作的压电振动给料器。通过对双悬臂式压电振动给料器进行简化,并建立其动力学模型,推导出固有频率以及装置振幅的表达式,分析了影响固有频率和振幅的因素。利用ANSYS Workbench软件对装置进行动力学分析,系统固有频率为118.85 Hz,并对装置进行了谐响应分析。结果表明,当驱动电压为200 V时,系统驱动频率为116.00~122.00 Hz,双悬臂式压电振动给料器具备输送物料能力,在最靠近共振点处(118.00 Hz)振动幅值最大,输送效率最高,满足工业生产的使用要求。

Abstract: Modern automatic assembly puts forward higher requirements for the stability and accuracy of material conveying. In order to meet industrial needs, a piezoelectric vibration that uses a rectangular piezoelectric vibrator as an excitation source and works in a vertical drive mode was designed. Feeder. By simplifying the double⁃cantilever piezoelectric vibrating feeder and establishing its dynamic model, the expressions of natural frequency and device amplitude were derived, and some factors affecting natural frequency and amplitude were analyzed. Use ANSYS Workbench software to analyze the dynamics of the device. The natural frequency of the system was 118.85 Hz, and the harmonic response analysis of the device was performed. The results show that when the driving voltage is 200 V, the system driving frequency is between 116.00~122.00 Hz, and the double cantilever piezoelectric vibration gives The feeder has the ability to transport materials, the vibration amplitude is the largest at the point closest to the resonance point (118.00 Hz), and the transport efficiency is the highest, which can meet the requirements of industrial production.
