Characterizing the effects of friction liner materials on the performance of piezoelectric motors using finite element analysis

摘要

A finite element model of a Panasonic USM-40D piezoelectric motor's rotor was coupled with a finite element model of the motor's friction liner/rotor so that the frictional interface could be further studied. Results from the model were used to study the affects of various friction liner material properties on motor stall torque. Statistical methods were used to determine the significant friction liner material properties and their interactions. An equation for predicting the stall torque as a function of the significant variables and their interactions was established.
