Design and Analysis of a Ultrasonic Sliding Platform


Article Preview

This article is meant to perform the simulation behavior of fluctuation and vibration for the ANSYS software against piezoelectric structure. From the relevant analysis, it can be aimed to devise the single-axis ultrasonic sliding platform inclusive of propeller system and sliding mechanism. Within both systems of propeller system and sliding mechanism, they are adopted with the piezoelectric buzzer as the material for driving components. The propeller actuator (propeller system), on the Ni-alloy plate of buzzer, will be divided to the non-axisymmetric structure at the respective angles of 90º, 120º and 150º with the resultantly produced radial vibration to move the platform. Also, the sliding vibrator (sliding mechanism) will be evenly divided into 3 parts of axisymmetric structure at the angle of 120º with its longitudinal vibration to reduce the friction caused by platform movement. In the designing process, it is adopted with the finite element analysis software - ANSYS to perform analysis and simulation for the vibration patterns of actuator and vibrator. By measuring the friction coefficient of sliding platform, it is well verified that the introduction of sliding mechanism will certainly reduce the friction caused by platform movement. The static friction coefficient will be reduced from 0.37 to 0.2 to result in considerably increasing displacement speed of platform.
