The automatic feeding device which is formed by combining the vibration disc and the linearvibrator is particularly suitable for precise machining on light and small parts.
By comparing the linear accelerometer's dynamic calibration device with linearvibrator, it pointed out the advantages of the former in the process of linear accelerometer dynamic calibration.
This paper presents two kinds of approximate analytical solution, non-resonance solution and resonance solution, of non-linear dynamic equation based on a type of ultra-low frequency vibrator.
