A Study of a Miniature Modularized Electro-Hydraulic High-Frequency Flutter

Abstract:

In order to solve the problem that traditional flutters can’t reach the requirements of vibration-assisted machining (VAM), a miniature modularized electro-hydraulic high-frequency flutter was proposed, which can output large force in high frequency. The structure and working principle of the flutter were elaborated in this paper. The equations of the valve in this flutter can be obtained based on equations of tradition valves, which established the mathematical model of the flutter. The flutter output waveforms were analysed by MATLAB in different input frequencies. The simulation results show that the flutter amplitude reach the maximum value in resonant frequency.
