| Summary: | Piezoelectric actuators are increasingly becoming popular
for the use in various industrial, pharmaceutical, and engineering
applications. However, their short motion range limits their wide
applications. This shortcoming can be overcome by coupling the piezoelectric
actuators with a mechanical displacement amplifier. In this paper, a new
design for a XY planar motion compliant mechanical displacement amplifier
(CMDA) based on the design of a symmetric five-bar compliant mechanical
amplifier is introduced. Detailed analysis with Finite Element Method (FEM)
of static and dynamic characteristics of the proposed XY CMDA design is also
provided. Finally, the optimization process and results to increase the
Amplification Ratio (AR) of the proposed XY compliant mechanism with minimal
compromise in Natural Frequency (NF) is discussed. |
