Abstract
In this paper, the optimum design and dynamic analysis of a new type of piezoelectric Braille display cell are studied by computer aided engineering software. At first, the design parameters of piezoelectric actuator are analyzed by finite element method to determine the position of fixed end and minimum voltage to actuate 0.7mm displacement and 15g output force. Then, the optimum design is performed according to the electric displacement 0.7mm, output force 15g, actuator length, position of fixed end and minimum voltage. Finally, Braille display cell is analyzed by dynamic simulation software. It shows that actuators take 0.0002 sec to upward achieve 0.7 mm displacement. The result of optimum design is reasonable in this paper which can be the reference for related research.
