This paper describes working principles of traditional ladder-type surface acoustic wave (SAW) filter composed by resonators. The simulation model was founded by utilizing Quite Universal Circuit Simulator (QUCS) for a seven stepped SAW filters on substrate of relaxor based ferroelectric single crystals. An extremely large wideband SAW filter of 620 MHz at 1 GHz could be obtained due to large electromechanical coupling factor (K2~60%) when the substrate is poled along (111) plane, which is presently three times larger than that achieved by conventional piezoelectric material. The band rejection could be improved by adjusting static capacitance ratio of series and parallel arm resonators. In order to optimize overall properties of the ultra-wideband SAW filter, we have modified the structure of a conventional ladder-type filter by adding a resonator to series or parallel arm to form two new notches, which sacrifices some bandwidth, but could achieve large transition band, steep transition zone and also band rejection. Finally, we discussed the influence of quality factor on the insertion loss of the SAW filters.

0.91Pb(Zn1/3Nb2/3)O3-0.09 PbTiO3 (PZN-9%PT) single crystal was grown by flux Bridgman method. The crystal was oriented and cut into several plates. The polished plate looks pale yellow with 50% transmittance. Strip-like and finger-like domains were observed using a polarized light microscopy. The evaluation of domains were observed using a high temperature metallurgical microscope and the results revealed the reversible process of domains from rhombohedral and tetragonal to cubic phases. Cary 5000 UV/VIS/NIR spectrophotometer was used to be measured the transmittance. The results show that two regions exhibit different transmittance.

Based on the theory of Biot's incremental deformations, the axisymmetric torsional wave controlling equation of the unidirectional composite hollow cylinder with uniform initial stress is deduced in this paper. The exact dispersion equation is obtained by the first and second Bessel functions. In order to illustrate the effect of the initial stress on the axisymmetric torsional wave in the unidirectional composite hollow cylinder, axial initial stress and radial initial stress are discussed respectively. Numerical results show that the effects of the initial stresses in axial and radial directions on axisymmetric torsional wave both are very regular and the effects of the compressive stress on dispersion curves are contrary to those of stretch stress, but the influential manners of the axial initial stress and the radial initial stress to the dispersion curves are different.

The thickness-shear vibration of c-axis tilted 430 ZnO thin film, one side of it is contacted with a layer of viscous conductive liquids is analyzed. The frequency equation has been derived from the three-dimensional linear piezoelectricity theory. The effects of conductivity on the shift in the resonant frequency has been analyzed and discussed in detail. By setting the density, the viscous coefficient and the thickness of the liquid as specified values, the relation of the shift in the resonant frequency and the conductivity is obtained. The present results demonstrate that the shift in the resonant frequency decreases with the conductivity in a special range. Analysis method and calculation results can provide important reference to the resonators design.

Ultrasonic guided waves are widely applied in non-destructive testing (NDT) due to its high efficiency, however, the inspection of large areas of complex structures can be challenging. Weld can be taken as a wave-guide because it can concentrate and guide energy of ultrasonic waves to travel along the direction of weld, which shows a potential for rapid NDE of long welds. In this paper, the effect of joint geometry parameters on two ultrasonic weld-guided modes, named the SHw0 and the Sw0 mode, in 10 mm thick steel-AISI-4340 plates has been analyzed through semi-analytical finite element simulations. Results show that the propagation properties of the SHw0 mode is almost stable with different geometry parameters. However, the phase velocity and attenuation of Sw0 will change with the increase of weld width and reinforcing height, which can be taken into consideration when we are choosing a mode as well as frequency in application of weld-guided waves.

This paper designed a hinged type beam clamping structure based on the characteristics of the Langevin-type transducer oscillator having obvious vibration node. The corresponding motor stator was developed based on the previous U-shape type linear ultrasonic motor. A simple mechanical model of the structure was established to analyze the effects of spring stiffness on the normal pressure and tangential friction force at the contact interface. Experimental results indicate that the output performance and stability of the motor reached a good state when the preload spring stiffness is sufficiently large and the preload is appropriate. Compared with the original arc clamping of the motors, the output force and speed of the motor were improved when the proposed hinged type beam clamping structure was adopted. The maximum no-load speed reached 712mm/s that increased by 51.5%, and the maximum force reached 10N that increased by 11.1%.

The method of reverberation-ray matrix (MRRM) is proposed for the analysis of in-plane Floquet wave propagation in general periodic laminated transversely isotropic composites. For this plane strain problem, by introducing the Floquet-Bloch principle, the formulation of MRRM giving the system equations is first derived based on the unit cell of the periodic multilayered media. The dispersion equation, which is used to compute the dispersion curves of the in-plane Floquet waves, is then obtained from vanishing the determinant of coefficient matrix of the system equation. Afterwards the numerical examples are given to illustrate the effectiveness of the proposed method in both low and high frequency range. From the numerical examples, the general features of the frequency-wavenumber spectra of the in-plane Floquet waves are finally summarized. The results obtained in this paper can be used to guide the design of periodic laminated composites for wave and vibration control applications.

In this paper, a 2D axisymmetric model was built to observe the acoustic field and electric potential distributions during the energy transmission process from a piezoelectric layer to a metal plate. The effect of dimension of the piezoelectric transducer on the energy transmission is compared and analyzed by using the COMSOL multiphysics. Then, an experimental platform is instituted to verify the feasibility of the method of energy transmission by acoustic wave through a metal plate. Based on the finite element simulation and experimental test, it is found that the power conversion efficiency is related to the size of the transducer, the thickness of the metal plate, and other parameters. It is shown by experimental measurement that the conversion efficiency could be reached about 30%.

A 3-DOF micromanipulator driven by linear ultrasonic motors is proposed in this paper. Compared with the traditional micromanipulator based on static deformation of piezoelectric ceramics (high displacement resolution, micro-size motion range), this micromanipulator owns motion range in millimeter size (2 mm) while having high displacement resolution (50 nm). First of all, working principle of the micromanipulator is described. Parallel mechanism is adopted in this micromanipulator, linear ultrasonic motors are taken as the sliding pair to actuate the micromanipulator and flexible hinge are introduced as revolute pair. Then kinematics analysis of the micromanipulator is carried out. Finally, a series of experimental studies are illustrated in detail, steel balls and shrimp roe had been grasped and moved by this micromanipulator under telescope. The experimental results show that the micromanipulator can be applied to grab and move tiny particles. This micromanipulator has good performance and can be used in medical and biological engineering field.
