End-to-end intelligent diagnosis of rotating machinery under speed fluctuation and limited samples is challenging in industrial practice. The existing methods usually focus on the data distribution or learning strategy with particularity. Generative adversarial network (GAN) provides a generation solution portability fault samples. However, GAN has problems gradient vanishing, weak extraction global features, redundant training. This article proposes dual-threshold attention-guided (DTAGAN)...
Although the existing generative adversarial networks (GAN) have potential for data augmentation and intelligent fault diagnosis of planetary gearbox, it remains difficult to deal with extremely limited training samples effectively fuse representative diverse information. To tackle abovementioned challenges, an improved local fusion network is proposed. Time-domain waveforms are first transformed into time–frequency diagrams highlight characteristics. Subsequently, a module used fully...
Current fault diagnosis methods for rotor-bearing system are mostly based on analyzing the vibration signals collected at steady rotating speeds. In those methods, data under one operating condition cannot be accurately used a different condition. Moreover, in monitoring, installing necessary sensors will affect equipment structure and hence response itself. The present paper proposes new method two-stage parameter transfer infrared thermal images of variable enables use (or parameters)...
Abstract The rotor systems of an aero engine will endure additional centrifugal force and gyroscopic moment during maneuver flight. A fly mechanical simulator is designed experimental investigations on dynamics squeeze film damper (SFD) under the different are carried out. results show that flight weaken effectiveness SFD, caused by change damping, stiffness. And influence can be effective relieved increasing clearance.
The nonlinear integral resonant controller (NIRC) is implemented and analyzed to control the vibration of a viscoelastic isolation system under harmonic excitation. NIRC consists first-order integrator, which provides additional damping in closed-loop reduce high-amplitude near resonance frequency. method multiple scales applied analytically find relationship amplitude–frequency response system. Besides, equation backbone curve satisfied derived. Meanwhile, suppression performance verified...
As one of the most common neurological diseases in world, epilepsy can be caused through deletion or duplication known epilepsy-associated genes. Therefore, it is crucial to accurately identify genes gain a deeper understanding pathogenesis and develop new therapies. Although number wet-lab experimental methods have been proposed, they are reliable but general time-consuming labor-intensive. Hence, their practical application identification quite limited. To address existing limitations, we...
To study the aerodynamic characteristics of strayed cable under wind and rain, with object Zhijiang bridge, pressure experiments on 2- 3-dimensional models stay cables in tunnel are made. Mean fluctuating wind-pressure coefficients 2 kinds surface morphology different direction angle obtained. The results show that rivulet position will greatly influence distribution surface, separation point flow nearby be changed obviously. Aerodynamic when a certain position, then rain-wind-induced...
