Paper Abstract

Piezoelectric actuators for diesel fuel injection are subjected to a highly transient square pulse voltage excitation. A treatment of this modeling problem provides insight into a stress field inside the stack, highlighting a possibility of tensile stresses developing immediately after an application and a removal of voltage. Modeling offers an opportunity for optimization of the stack geometry for the best performance and response under the constraints of available space envelope, peak electric current and compressive prestress.
