Testing Mechanical and Electrical Defects in Piezoceramic Materials Resulting from Ultrasonic Vibrations

Abstract:

The work presents recommendations related to the selection and installation of high power piezo ceramic rings dedicated to simultaneous power supply and data transmission for the purpose of extending life in their operation. Mechanical and electrical defects in piezoceramic elements of conical actuators were presented. The issue is important in the case when energy and information are transmitted at the same time using upper acoustic waves to autonomic wireless measurement nodes (WMN) in mechanical construction elements. A laboratory ultrasonic actuator was made and used to test ceramic rings. Additionally a dedicated vibration sensor was made and a measurement system for determination of frequency response of high power actuators was developed. Identification of the material used to make the ceramic rings and feeding electrodes was conducted. Next calibration tests of conical piezoelectric actuators were conducted and their defects were tested.
