| | ABSTRACT | | IDM can be defined as the transformation of small vibrations of a piezo element into continuous
linear motion on a frictional surface by controlling the extension and contraction speed thus the
impact force. In most of previous studies, longitudinal vibrations of piezo elements are employed as in
[1], [2], [3] to obtain a continuous linear motion.
In this study, linear continuous motion characteristics of series connected piezoelectric (PZT)
crystals are investigated both numerically and experimentally, when the method of the impact drive
mechanism applied was driven by coupled transverse and torsional vibrations. For the experiments,
PZT rectangular crystal bars are series connected with a neodymium magnet glued to the bottom
end, and then positioned to a grinded smooth steel surface. The three test specimens were series
connected one, two, and three-elements PZT-5X military grade single crystals, and the neodymium
magnets were N38 grade coated with nickel. Before starting the tests, resonant frequencies of test
specimens are calculated numerically by making harmonic analysis employing a finite element
software (ANSYS) and tested experimentally by using the sweep characteristics of the signal
generator. Triangular, and sine signal waves at resonance frequencies are applied for each test
specimen at 220 Volts. Both the numerical and experimental results showed that the top-end
deflection, strain energy, the impact force thus the linear velocity increases by increasing the number
of PZT crystal elements of a test specimen.
The research conducted here could be supportive when designing nano/micro-scale positioning
actuators and driving systems for different kinds of high technology applications. |
