It can be concluded that the finite element modelling can be used as a new tool for scientific investigation of this material in various form. The mode shapes and natural frequencies at specific frequency spectrum are also presented. The results show that the behaviour of the piezoelectric element for various electric excitation and motor vibration depends on the different frequency range. A 3D finite-element model is developed with piezoelectric patches, which are surface bonded on a thin quadrilateral plate and supported with spring damper elements. The goal of this paper is to present a new approach using a finite element formulation for the piezoelectric element as an aiding tool for an analytical approach to estimate the system transfer function. The transfer function is complicated to be determined using an analytical approach, especially for a thin structure with embedded actuators and sensors. The control of the piezo element system requires knowledge of transfer functions between the input and the output of the system. The major ones are space and newspace, optronics, scientific instrumentation, production and manufacturing and medical technology.Īll these application fields gather round advanced functions requiring fast or precise actuation: precise positioning, fast displacement, vibration/force generator, vibration damping.Īpplications, customized actuators or new solutions are presented in the section Applications and Piezoelectric Actuators Technologies.The piezoelectric element can be used both as actuator and sensor. Our piezo actuators find applications in all the fields of mechatronics. Amplified Piezoelectric Actuators (APA®).In order to meet varying customer actuation specifications, CEDRAT TECHNOLOGIES has developped different families of standard piezoelectric actuators with their corresponding drivers and controllers: The Piezoelectric Actuators developed by CEDRAT TECHNOLOGIES have the following outstanding characteristics: high force and large displacement in compact sizes, high resolution within the nanometre range, very short response time below 1 ms, life time greater than 10 10 cycles, low voltage supply below 150V DC, no backlash and no play, low power consumption when static, severe environment compatibility (vacuum, cryogenic, high temperatures,…).
