摘　　要：为获取不同驱动波形下压电陶瓷喷头喷射墨滴的行为参数,传统方法通常凭借经验手动调节仪器,并通过墨滴观测仪进行多次实验。这一过程耗时且精度不足,难以满足精细化控制的需求。为解决这一问题,本文基于数值模拟方法,构建了压电陶瓷喷头的仿真模型。该模型综合考虑了喷头的工作原理,详细模拟了压电陶瓷的形变、墨腔壁的应力响应以及喷嘴内部的流场变化。通过该仿真模型,深入分析了不同驱动电压波形对墨滴行为参数的影响,包括墨滴的速度、质量、喷嘴处的压力以及喷射状态。此方法能够实现对墨滴行为及其形成过程的精确模拟,克服了传统手动调参中存在的不确定性和低效性,显著提升了对墨滴喷射过程的控制精度和效率。To accurately obtain the droplet behavior parameters of a piezoelectric ceramic printhead under different driving waveforms,traditional methods often rely on manual instrument adjustments based on experience and require multiple experiments using a droplet observation system.This process is time-consuming and lacks sufficient precision,making it difficult to meet the requirements for fine control.To address this issue,this paper constructs a simulation model of a piezoelectric ceramic printhead using numerical simulation methods.The model comprehensively incorporates the operating principles of the printhead,simulating the deformation of the piezoelectric ceramic,the stress response of the ink chamber walls,and the fluid flow field inside the nozzle.Through this simulation model,the effects of different driving voltage waveforms on the droplet behavior parameters,including droplet velocity,mass,nozzle pressure,and ejection state,are analyzed in detail.This method enables precise simulation of the droplet behavior and formation process,overcoming the uncertainties and inefficiencies associated with traditional manual parameter adjustments,and significantly improves the accuracy and efficiency of droplet control.
