Fault diagnosis and classification (FDC) is an important part of prognostics health management for ensuring safety performance in the flight. However, it challenging to achieve accurate FDC only based on single senor readings. In this paper, a fused model among multiple different sensors stabled by hybrid deep learning architecture combining sparse autoencoder (SAE) convolutional neural network (CNN). The uses SAE enhance hidden fault signal features sensor signals, then classifies obtained...
Abstract Fault diagnosis of multi-source signal systems is critical for the safe and reliable operation modern industrial systems, accurate fault based on signals remains challenging. This study proposes a data-driven hybrid detection/diagnosis method to identify sensor faults in complex through interactions between multiple sensors. Dynamic mode decomposition with control used obtain approximate model investigated system from signals, extract underlying physical mechanisms, combined Kalman...
<title>Abstract</title> The wake dynamics of the flow past a confined circular cylinder and its active control by sweeping jets (SWJs) steady (SJs) positioned at front stagnation points were experimentally investigated using Particle Image Velocimetry (PIV) pressure measurements. Experiments conducted across range Reynolds numbers (Re) from 10,000 to 45,000 blockage ratios (β) \(1/2\), \(1/3\), \(1/4\), \(1/5\). A comprehensive comparison between current results existing literature on...
In order to resolve the resonance problem of jack-up riser with drill string, frequency equation natural transverse vibration compressive axial load and length above seabed as independent variable was derived in this paper.Then solved by Newton method, accuracy calculation method without analyzed.In addition, a resonant rotating speed table top-drive system (TDS) made according relationship between frequency.The results show that: proposed paper is more accurate than Rayleigh method;...
Abstract The present study optimized some novel fluidic oscillator designs, measured their internal-external fluid dynamics, and used modal analysis to reveal underlying oscillation mechanisms. It also investigated the effects of structural parameters on dynamics. time-resolved pressure fields oscillators were determined by using pressure-sensitive paint (PSP) measurement. Proper orthogonal decomposition (POD) dynamic mode (DMD) for phase reconstruction. time-averaged pressure-field...
