Alternating current field measurement (ACFM) and eddy thermography are two non-destructive testing (NDT) methods widely used in industries. In this study, a combined NDT method based on the is proposed. Firstly, some relative mathematical models provided, then an experimental system designed for combination of methods. The obtained magnetic signal smoothed by double moving average crack identification location realised using morphological characteristics Bx curve. Then, thermal images...
Dynamic performance of sandwich beam with shear thickening fluid (STF) core subjected to a periodic excitation is investigated. The addition STF enables the have tuning stiffness and damping capacity under dynamic deformation. Here, constitutive model described by complex modulus related rate. transverse moving modeled based on Newtonian law derived nonlinear equations are solved finite difference method. It found that resonant frequency increases amplitude external power law. In addition,...
The anomalously low‐friction effect is a key scientific problem in deep mining. coal rock media usually block structure with joint fracture. When the subjected to repeated strong dynamic impact caused by long‐term excavation activities, will occur, resulting disasters such as bursts. Taking granite research object and using bidirectional loading simulate disturbance of media, numerical model was established. vertical acceleration horizontal displacement on working were defined characteristic...
The vibration responses of a sandwich beam with partially covered by shear thickening fluid (STF) layer under an impact load are investigated. nonlinear governing equations the flexural derived based on extended Hamilton’s principle and solved finite difference method. model is then validated used to develop complete parametric study beams STF-filled core properly design place STF patch. It found that, for first mode, maximum damping, smallest change in natural frequency achieved when...
Wood, as a natural material, inevitably contains initial defects such knots, cracks, and decay, which are important factors affecting its mechanical properties cannot be ignored. In order to investigate the influence of on compressive wood, Norway spruce was selected research object. Wood specimens without with were prepared, uniaxial compression tests conducted. Combined Digital Image Correlation (DIC) finite element analysis, defective wood studied. The results showed that compared...
AbstractThe dynamic performances of a sandwich beam with shear thickening fluid (STF) core subjected to random excitation are investigated. First, the STF is prepared and new constitutive model proposed based on oscillatory rheological measurements. Next, flexural vibration an under load developed, parametric study carried out. It found that response frequencies damping ratios for first three modes increase standard deviation external excitation. The provides better larger broadband...
Abstract Abstract.This paper introduces the serious crack accident of rotor a 600 MW turbo-generator unit in Vietnam, which leads to scrapped. After excluding material and design reasons, it is considered that electrical torque possibility. Through operation parameters theoretical calculation unit, fault reason positioned as Sub-synchronous resonance. The most important criterion vibration Unit 1 increases simultaneously with 2, physically isolated from 1. Further shows natural frequencies...
The function of components and the theory oil-paper capacitive bushing are introduced by analyzing its contracture, electric properties insulation materials instructed.The reasons damages lack oil proper illustrated, judging methods offered.The distinguishing process is illustrated examples, accuracy rationality finding volume, dielectric loss angle, chromatogram infrared ray test demonstrated.
In this paper, we present the process of modeling for virtual tobacco growth, which is abstract and summarize our group previous work. Then discuss three key parts modeling: geometrical structural model, topological model ecophysiological rules model. Especially introduce quanta theory to obtain more precise according. At last, make experiment, validates theory.
