Modeling and Numerical Simulation of the Crosstalk Behavior of a DOD Printhead
Abstract:This paper reports the modeling of a given printhead with piezoelectric bend mode actuators. The model describes the electric, mechanical as well as the fluid dynamic characteristics of the printhead. The electric and mechanical parts of the piezoelectric bend mode actuator are described by conventional lumped elements which interact as constituent parts of a Kirchhoffian network. The complex three-dimensional fluid analysis is performed by a commercial computational fluid dynamics (CFD) free-surface modeling package. The fluid structure coupling is realized by exchanging of data between the electro-mechanical model and the fluid simulation tool for every numerical time step.
The piezoelectric printhead has been computationally simulated to analyze the fluid flow dynamics and the jet forming process. Moreover inter-channel crosstalk caused by interconnected fluid channels of the printhead is studied. As a result, this paper discusses the fundamentals of the crosstalk problem and shows ways for crosstalk compensation methods based on optimized compensation drive pulses.
