This paper presents a new mechanism for circular flexture traveling wave excitation, which is based on shear-shear mode in single piezoelectric disc with center hole was poled along its radial direction. Its bottom electrode divided into four parts, and the top acted as common ground. By use of pair alternating current (AC) voltage signals (sine cosine), at disc's resonance frequency, flexural generated circumferentially. Both finite element modeling (FEM) analysis transducers by integration...
The interesting properties of water molecules confined in a two-dimensional (2D) environment have aroused great attention. However, the study 2D-confined at hydrophilic–hydrophilic interface is largely unexplored due to lack appropriate system. In this work, behavior between an atomically thin mica nanosheet and hydrophilic SiO2/Si substrate was investigated using atomic force microscope detail ambient conditions. aggregated as droplets when relative humidity (RH) 11%. A large-area 2D film...
Mango is soft in texture. When it picked or ripened, may be eroded by pests damaged when falls on the ground. A mango surface defect detection device based HALCON was designed to improve accuracy and efficiency. image acquisition system built using CCD array camera, LED light source switching power supply obtain high-definition of mango. software used preprocess original image, threshold segmentation, morphological denoising so on. Finally, target features are extracted area calculated. The...
The piston of the engine is inevitably accompanied with vibration during its operation process, so it particularly important to study static and modal characteristic. three dimensional model imported into finite element analysis software ANSYS Workbench. carried out. equivalent stress, deformation, natural frequency mode are obtained. results provide reference basis for research improve efficiency design shorten time.
During the past two decades, we have designed and fabricated a large family of composite ferroelectrics for use as sensors, actuators, transducers. These devices employ stress strain amplification mechanisms provide superior acoustic matching to seawater human body. Recently concentrated on flat-panel arrays thinner than 3 mm constructed from miniature flextensional transducers (Cymbals) or small hollow sphere (BBs) embedded in polymers. This paper focuses fabrication BB spheres. Millimeter...

Gear pump is a very common hydraulic used in industrial production and life. has many advantages, such as compact structure, small volume, light weight, wide speed range, stable performance so on. But gear flow pulsation, oil leakage, meshing trap other shortcomings. In this paper, based on certain an example, using ANSYS Workbench related software, the modeled by CATIA, finite element analysis method carried out to analyze deal with problems. Surveying mapping gears, modeling, The software...
Abstract Due to the randomness of ground motion and variation material itself, it is unreasonable regard inter-layer target displacement angle structure as a certain amount in direct displacement-based seismic design. In this paper, an improved design method proposed, which characterized by: (1)Considering reliability when determining between layers, combining probability characteristics has meaning.(2)According quantitative relationship damage index ductility, structural performance target,...
