| 中文摘要: |
| 为得到期望的喷射墨滴，分别针对油墨特性中3个具有代表性的参数：韦伯数、雷诺数及奥内佐格数进行了分析，给出了适用于新技术领域的油墨特性范围，同时针对标准脉冲在喷墨头上应用所存在的残余波动问题，通过建立离散时间模型的方法设计出了一种优化脉冲，然后根据墨滴喷射时弯液面速度的变化情况，将标准脉冲和优化脉冲下墨腔中残余波动的影响进行了实验对比分析，发现在优化脉冲驱动下喷射出的墨滴更符合实际需求。 |

| To achieve desired jet drops, Weber number, Reynold number and Ohnesorge number, which are the three representative parameters of ink characteristics, were analyzed respectively and the new ink characteristics range applicable to the new technology area were given. An optimizing pulse was designed by establishing discrete time model method to solve the existing residual fluctuation problem caused by standard pulse in inkjet head. According to the change of curved liquid surface speed during drop injection process, the residual fluctuations in the ink cavity were compared and analyzed under the standard pulse and optimizing pulse. It was proved that the ink drops driven by optimizing pulse is more in accord with actual needs. |
