Structure Analysis and Optimization Design of Driving Foot Based on ANSYS Workbench

Abstract

Driving foot as the energy transfer mechanism in linear piezoelectric motor and the mechanical output characteristics has an important role in linear piezoelectric motor’s output. In order to improve the driving foot structure design method, the equivalent stress, deformation and modal of the driving foot structure are simulated and analyzed based on the ANSYS Workbench, and the amplification factor of driving foot is optimized. After optimizing the magnification of driving foot is 7.6, the maximum equivalent stress is 86MPa and the first-order natural frequency is 7119Hz.
