Modeling and Simulation of a Jet Dispenser Based on GMA

This paper introduces the structure and working principle of a jet dispenser based on giant magnetostrictive actuator(GMA), builds the mathematics and simulation model of the jet dispenser, researches its dynamic characteristics and analyses the simulation results. The simulation results show that the needle displacement, needle velocity and accumulated fluid volume are consistent with actual situation. It demonstrates that the model can correctly reflect the dispenser's dynamic characteristics.
