To solve the problem of false defect detection owing to interference texture attribute ceramic tiles, a method for detecting surface defects in complex-textured tiles is proposed. Based on visual principle tile surfaces, an image acquisition system established obtain image. After segmentation and correction, are preliminarily detected using saliency method. Then, sub-block containing area cut out secondary detection. The eliminated, final completed determination feasibility effectiveness...
Abstract Lamb waves can be divided into antisymmetric (type A) and symmetric S), which are widely used in health monitoring of engineering structures nondestructive evaluation materials. However, due to the fact that each mode wave has setting group velocity a certain bandwidth range, it is easy cause aliasing multi-mode waves, partly limiting application scenarios wave. In this paper, hexagonal lattice meta-structure designed zero-order (S 0 ) finite thickness plate successfully separated....
The basic vibration generated during the tunneling process of hard rock tunnel results in change support stiffness hydraulic pipe, which causes problem reduction pipe transmission efficiency. A transverse motion equation was established by correlating with Hamilton’s principle under vibration. In consideration fluid‐structure interaction (FSI), simplified as an equivalent and a spring. bidirectional fluid‐solid coupling analysis method used to investigate dynamic characteristics pipeline...
This paper studies the dynamic response of a pipe conveying pulsating fluid under random vibration. Its nonlinear equation motion is first developed using method Newton. The Galerkin then used to discretize into system ordinary differential equations. Afterwards, statistical moments and mean peak values displacement velocity responses are obtained an efficient Monte Carlo simulation (MCS) based on explicit time-domain (ETDM). Furthermore, displacement-sensitive velocity-sensitive locations...
In this paper, the fluid pressure responses of hydraulic composite pipe subjected to an axial random vibration are investigated. First, motion equations under established, considering fluid–structure interaction. Second, characteristic line and pseudo-excitation methods for employed solve dynamic characteristics. Finally, influence laws velocity pressure, external excitation, structure parameters analyzed. The results demonstrate that analytical method is beneficial analyze vibration, which...
Purpose To improve the transmission efficiency and reduce damage to pipes in hydraulic systems of tunnel boring machine subjected random vibration, this paper aims propose a novel dynamic characteristic analysis method that considers vibration. Design/methodology/approach A fluid-structure interaction motion equation pipe is established by using Hamilton’s principle. The finite element discrete vibration are used construct model behavior pipe. Findings influences fluid parameters external...
Ratcheting deformation is studied on elbow pipe made of Z2CND18.12N by FEM software. The simulation conducted ANSYS. Chen-Jiao-Kim (CJK) kinematic hardening model added in ANSYS for the study. subjected to internal pressure and reversed in-plane bending. Internal can be constant or cyclic. Many different loading paths are used deformations under ways studied. result shows that ratcheting occurs mainly circumferential direction. at crown intrados more notable because higher stress. Tensile...
