“…It consists of piezoceramic rings sandwiched between matching end and front mass. This construction is mechanically prestressed by a centre bolt, which provides enough preload to the piezo rings to avoid any fractures on the expansion of piezoceramic [5]. One-dimensional and combined vibrations like longitudinal-flexural, longitudinal-torsional, and flexuraltorsional can be generated by a single device and employed on the tool for applications like ultrasonic vibration-assisted drilling, milling, and polishing [6,7].…”

Ultrasonic vibration–assisted machining (VAM) is a process in which a tool or workpiece is vibrated using ultrasonic frequency small-amplitude vibrations to improve cutting performance, and an ultrasonic transducer usually generates these vibrations. This study investigates how two-dimensional vibrations are generated using axially polled piezoceramics. Modifying the wave propagation in geometric ways by creating a notch at the front mass, the longitudinal response excited by the axially polled piezoceramic discs can be converted into combined longitudinal and bending vibrations at the transducer front mass. Finite element analysis (FEA) software COMSOL is used to study wave propagation, and ANSYS is used to optimize the transducer’s mechanical structure, while an equivalent circuit approach is used to analyze the electrical impedance spectra and confirm its resonance frequency. An experimental analysis of impedance response and amplitude of generated vibrations using the novel 2D ultrasonic transducer is conducted to validate the numerical and analytical results, which shows that resonance frequency results are in very good agreement with the theoretical model. Finally, the proposed design is validated by preliminary test results that demonstrate its performance and principles.

“…Experimental results indicated that the measured resonance frequency of the transducer was in good agreement with the theoretical value. Arnold (2008) In this paper, the transducer and the horn were designed as a whole, in other words, an ultrasonic transducer with a quarter-wave taper transition horn was designed based on the equivalent circuit method. Meanwhile, the equivalent circuit of the transducer was adopted to obtain its mechanical responses and electrical characteristics.…”
