Design of a Micro-Nano Positioning Platform Based on Stick-Slip Driving
Abstract:
Micro-nanopositioning platform is a core component for micro-nanooperation. The static and dynamic characteristics of platform will determine its precision level. This paper presented a new 2-D micro-nanoplatform based on stick-slip driving. By using static structural module and modal analysis module of ANSYS software, the stress and natural frequency of pedestal were analyzed. The driving frequency of piezoelectric ceramic was selected far away from the natural frequency to avoid resonance. Dynamic performance of pedestal was also analyzed with ANSYS transient module. Simulation results show that the presented platform has excellent static and dynamic performance.
