螺旋式压电振动给料器的模型建立与实验研究
Study on model and experiment of spiral piezoelectric vibration feeder
摘要
Abstract
This paper expounded the selection of piezoelectric materials , the piezoelectric characteristics of double chip , discusses the spiral of piezoelectric vibrator used piezoelectric vibration feeder , and the vibration model of piezoelectric vibrator .Spiral vibration model of piezoelectric vibration feeder was established .The frequency of the feeder expression was ob-tained through the analysis of force of the material on the tray .The resonant frequency was 224.609 Hz as a result of prototype testing , and the characteristics curve of frequency and conveying speed is obtained by experiment .The experimental results showed that:when the voltage was 200 V, the frequency was about 220 Hz, the rate of conveying material was 83/30 s and the frequency was between 160 Hz and 280 Hz, the system has the ability of conve-ying material.The delivery rate was fastest under the condition of resonance (224.609 Hz).关键词
