The importance of strength design for devices is growing with the miniaturization
and flattening of electrical equipment and measures to reduce vibrations
are in even greater demand.To understand the characteristics of electrical
equipment, the vibration characteristics and strength of each part that
make up the device need to be accurately evaluated. Therefore, the phenomenon
of each individual part needs to be correctly analyzed first.This example
presents the use of a structural analysis to obtain eigenmodes and displacement
that has a concentrated load for 3 types of mesh models of a simple cantilever.
These results are then compared to the theoretical values.

Piezoelectric elements are used as actuators and sensors, as well as oscillator circuits and filter circuits in the analog electronic circuits. When the electric potential is applied, the piezoelectric element is deformed. This is called the converse piezoelectric effect. In JMAG, the analysis of the piezoelectric actuator using the converse piezoelectric effect can be performed by specifying the permittivity matrix and the electric potential for the material.
This note presents the use of structural analysis to evaluate the displacement of a bimorph piezoelectric actuator, caused by the inverse piezoelectric effect.
