“Vibration characteristics
of piezoelectric transducer”
Synopsis:
Piezoelectricity is one of the phenomena of
nature that makes possible the changing of one form of
energy to another form - in
this case mechanical
motion is converted
into an electric potential. By
definition, piezo-electricity
is the electricity (electric charge) generated in
a material when
mechanical pressure is applied to it. The opposite effect also occurs;
the material changes its
physical shape when an electric charge is applied. These two basic effects are the foundation of
piezoelectricity.
All materials
found in nature are not
piezoelectric; only those materials lacking a center of symmetry on the
atomic scale can be piezoelectric. Examples of piezoelectric materials include
quartz, Rochelle salt, and lead -- titanate – zirconate ceramics.
One
of the major applications of piezoelectricity is in transducers. A transducer
is any device that converts mechanical energy into a corresponding electrical
signal. It may also work in the opposite direction, changing electrical to
mechanical energy. One of the common applications of piezoelectric transducers
is in the measurement and analysis of vibrations characteristics of engineering
structures.
The
major objectives of the current project work are:
1. To carryout a compressive literature survey on
piezoelectricity, piezoelectric materials and their applications;
2. To provide an over view of Finite Element Method
(FEM) in structural analysis;
3. To develop an FEM model and study vibration
characteristics of a piezoelectric transducer and
4. To compare FEM results with published results.
Finite Element techniques will be used in the
analysis. The front-end commercial software ANSYS with its
coupled field analysis capabilities
will be adopted. The FEM mesh
will be generated using SOLID5 element and
analysis technique used
will be Reduced (Householder)
method.
Some
important results of the research investigations:
