Design and Fabrication of a Longitudinal-Torsional Ultrasonic Transducer
A hybrid longitudinal-torsional ultrasonic transducer is designed and fabricated in this research. The design of the transducer was performed using the FE method with ABAQUS software, with the aim of combining the longitudinal and torsional vibration modes. The transducer horn is then fabricated using a 4-axis milling machine. The PZT stacks are employed in order to excite the transducer. The t...

متن کاملDesign and Test of Capacitive Micromachined Ultrasonic Transducer
Currently, most capacitive micromachined ultrasound transducers, adopting surface sacrificial technology encounter various problems such as difficult cavity etch, low controllability of membrane thickness etc., and their operating frequencies are more concentrated in several MHz bandwidths that cannot meet the requirements of long-distance imaging applications. In order to solve these problems,...
متن کاملPiezoceramic Element Design and Fabrication for Ultrasonic Transducer of Gas Meter
Ultrasonic transducers play a significant role in generating and receiving the acoustic waves in ultrasonic flowmeters. Depending on the required accuracy, the ultrasonic transducers can be installed either in one pair or more in an ultrasonic flowmeter. The main part of an ultrasonic transducer is its piezoceramic element. In this work, four piezoceramic elements with different diameter to thi...
متن کاملDesign of ultrasonic wedge transducer q
Cones and wedges inserted between an ultrasonic transducer and the specimen provide the transducer (circular or rectangular shape) with enhanced capability for point or line contact with the specimen. Such an arrangement is useful in that the transducer can be used for transmitting to and receiving from a point (or line) source, and that it can eliminate the undesirable aperture effect that mak...
