摘要

针对压电喷墨过程中墨水的黏度对喷墨质量造成的液滴拖尾、卫星墨滴和墨带的问题，提出一种压电喷墨过程动力学建模与供墨方法。基于流体体积模型，建立面向墨滴喷射物理过程的动力学模型。基于该模型，对墨滴生成、断裂以及飞行的过程进行数值模拟，通过不同的边界条件设定，分析墨水特性对液滴喷射的影响因素，得到喷头工作的最佳黏度范围。通过控制温度调节墨水特性以及控制液位调节供墨压力的方法，设计一种基于微机控制的独立供墨子系统。采用模糊PID算法，实现了对墨水温度的快速、平滑响应控制，得到了良好的墨水特性和供墨特性的控制效果。搭建了压电喷墨试验平台，得到了微滴喷射过程中完整微滴的形成过程以及典型特征，验证了本文方法的有效性。

Abstract

In view of the piezoelectric ink-jet ink viscosity in the process of the quality of ink-jet droplet trailing, satellite drops and the problem of ink ribbon, a kind of piezoelectric ink jet process dynamics modeling and ink methods is put forward. Based on the fluid volume model (VOF) is established the dynamic model for drops sprayed physical process. Based on this model, the generated drops, fracture, and is used to numerically simulate the process of flight, through the different boundary conditions are set, analyzed the influence factors of droplet spray on ink features, get the best viscosity range nozzle job. By controlling the temperature adjustment ink characteristics and control method of liquid level control for the ink pressure, a kind of independent for ink system based on microcomputer control is designed. Using the fuzzy PID algorithm to achieve the fast and smooth response of the temperature control of ink and the good characteristics of ink and ink control effect are got. Piezoelectric ink jet experiment platform, set up the complete in the process of droplet spray droplets forming process as well as the typical features of the effectiveness of the method is verified.
