“…This strategy based on the characteristics of the admittance circle of PT effectively avoids the influence of the system variation and brings better accuracy and faster tracking speed than traditional PLL-based methods, especially under low power consumption conditions. Furthermore, H. Zhang et al [177] proposed an artificial neural network method to characterize the response performance based on the radial basis function, which extracts the peak overshoot percentage and settling time from the harmonic excitation response signal of the transducer. This method can predict the new resonance frequency and provide support for the control system.…”

“…In the late 1980s, Lin Z M, an ultrasonic research expert from Shaanxi Normal University, compiled the principle and the design of the ultrasonic horn, which laid the teaching foundation in the domestic ultrasonic field [5]. In 2020, Zhang H J of Tiangong University optimized the resonance performance of the energy converter at different temperatures [6], and Hu G H of Henan University of Science and Technology designed a longitudinal bending composite two-dimensional ultrasonic transducer using finite element analysis [7]. In 2021, Hu T et al of Sichuan University studied a design method of a full wavelength piezoelectric ultrasonic transducer based on the mechanical quality factor given the problems of many size parameters and complex calculation caused by the conventional design method of transducer [8], and Xu L of China Jiliang University proposed a design method for radial vibration of stepped ring piezoelectric transducer [9].…”

When designing the horn of the ultrasonic transducer for rotary machining, the traditional analytical method cannot consider the complex assembly cross-section of the horn, resulting in a large final simulation error and design error. At the same time, when the design diameter of the transducer is too large, the size of the back mass obtained by the traditional analytical method is too thin. This paper combines the four terminal network method and the finite element method, selects the sandwich piezoelectric transducer, takes the ER spring chuck commonly used in rotary machining as an example, derives the transmission matrix corresponding to the geometric cross-section shape, and then uses the four-terminal network method and the traditional analytical method to design two sets of stepped ultrasonic transducers with the design frequency of 22 kHz for analysis and comparison. Finally, through the analysis, it is verified that the ultrasonic transducer designed by the four-terminal network method has a performance closer to the theoretical design.

“…Many real-life applications, such as transducers, pressure sensors, actuators [1], ultrasonic [2][3][4], medical [5,6], and automobile structures [7,8], use piezoelectric materials due to their distinct characteristics and unique electrical, mechanical, chemical, and thermal properties. The piezoelectric materials possess two important phenomena: direct piezoelectric effect, in which the mechanical energy is converted to electrical energy, and converse piezoelectric effect, where the electrical energy is converted to mechanical energy [9].…”

This paper aims to study the hygrothermal buckling of smart graphene/piezoelectric circular nanoplates lying on an elastic medium and subjected to an external electric field. The circular nanoplates are made of piezoelectric polymer reinforced with graphene platelets that are uniformly distributed through the thickness of the nanoplate. The material properties of the nanocomposite plate are determined based on the modified Halpin-Tsai model. To capture the nanoscale effects, the nonlocal strain gradient theory is applied. Moreover, the principle of virtual work is employed to establish the nonlinear stability equations in the framework of classical theory. The differential quadrature method is utilized to solve the governing equations. Among the important aims of the paper is to study the influences of various parameters such as graphene weight fraction, elastic foundation parameters, external applied electric field, humid conditions, and boundary conditions on the thermal buckling of the smart nanocomposite circular nanoplates. It is found that the increase in graphene components and elastic foundation stiffness enhances the strength of the plates; therefore, the buckling temperature will increase.
