由于墨水通道中的残留振荡，按需滴墨(DoD)喷墨打印头提供的打印质量受到限制。通过快速衰减残留振荡并以这种方式使墨水通道在喷射墨滴后静止，可以提高DOD喷墨打印头的最大喷射频率。本文提出了一种基于优化的方法来设计压电致动器的输入激励波形，以提高残余振荡的阻尼。由窄间隙模型导出的离散时间传递函数被用来预测在压电输入作用下墨道的响应。仿真和实验结果表明了该方法的可行性。(C)2011爱思唯尔有限公司。保留所有权利。
The printing quality delivered by a drop-on-demand (DoD) inkjet printhead is limited due to the residual oscillations in the ink channel. The maximal jetting frequency of a DoD inkjet printhead can be increased by quickly damping the residual oscillations and by bringing in this way the ink channel to rest after jetting the ink drop. This paper proposes an optimization-based method to design the input actuation waveform for the piezo actuator in order to improve the damping of the residual oscillations. A discrete-time transfer function derived from the narrow-gap model is used to predict the response of the ink channel under the application of the piezo input. Simulation and experimental results are presented to show the applicability of the proposed method. (C) 2011 Elsevier Ltd. All rights reserved.
