摘要

设计并加工了一种压电式微滴喷头，并在微滴喷射平台上进行了微滴喷射实验，用CCD相机拍摄到了液滴形成的整个过程。通过激光位移测量平台测量了压电片的振荡曲线，并将位移曲线输入流体模拟求解器，用两相的方法模拟出了微滴形成的过程。模拟显示液滴的形成时间，大小，形状和速度与实验结果拟合得很好。通过对比液滴的形成过程与压电片的振荡曲线，发现主液滴在压电信号为高电平时，已经脱落了微滴喷嘴，基于此提出了通过改变高电平时间和增加压电片的自由振荡衰减阻值提高微滴喷射最高频率的方案。通过微滴喷射行为模拟，解释了微滴喷射实验中出现两条液滴的原因，并通过改变喷腔结构和改变液体黏度，找到了减少额外液滴出现的途径。

Abstract

A piezoelectric printhead was designed and fabricated for Drop-On-Demand(DOD)printing. The formation of a droplet was captured by a CCD camera in the jetting experiment on a droplet jetting platform. The deformation curve of a piezoelectric plate was measured by a laser displacement sensor and it then was inputted into a flow simulation solver to simulate the process of droplet jetting with the methodology of free surface volume of fluid. The results show that the formation time

size and the volume and speed of the droplet simulated are in agreement with that of experiments. In the contrast between the formation process of droplet and the displacement curve of piezoelectric plate

it is found that the main droplet has dripped off the nozzle before the end of a high voltage

which can be used to improve the maximum frequency of droplet jetting by reducing the high voltage time and increasing the damping vibration resistance value of piezoelectric plate. The simulation of droplet jetting can also explain the formation mechanism of additional droplets in the experiment

and can successfully reduce the additional droplet by changing the structure of printhead and th e viscosity of forming materials.
