Bearing performance degradation assessment and prognostics are extremely important in supporting maintenance decision guaranteeing the system's reliability. To achieve this goal, paper proposes a novel feature extraction method for of bearings. Features time-frequency codes (TFCs) extracted from distribution using hybrid procedure based on short-time Fourier transform (STFT) non-negative matrix factorization (NMF) theory. An alternative way to design health indicator is investigated by...
Data collected from the supervisory control and data acquisition (SCADA) system are widely used in wind farms to detect turbines’ (WTs) faults. However, it is challenging extract performance trends provide accurate alarms based on SCADA with large operating conditions fluctuations. This article presents a fault detection frame of subspace reconstruction-based robust kernel principal component analysis (SR-RKPCA) model for turbines nonlinear features under discontinuous interference. First,...
Remanufacturing has attracted a lot of attention as the best form resource utilisation for used products and important way energy saving emission reduction. In this article, version production planning problems with remanufacturing back-ordering is discussed, in which there are multiple factories cooperative relationship to produce new products, or remanufactured ones, both. And all transported different demand sites, but allowable. For problem, three models proposed. The first model basic...
Purpose The purpose of this paper is to monitor the environmental efficiency suppliers in presence undesirable output and dual-role factors with static dynamic aspects. Meanwhile, it also aims explain main reason for low suppliers. Design/methodology/approach authors propose a modified data model considering factors. study integrates envelopment analysis into distance function Malmquist–Luenberger index. Moreover, uses global benchmark technology formulate two-stage model. To verify validity...
An original equipment manufacturer is studied, which makes new products and re-products (remanufactured refurbished products) simultaneously. Facing the product diversity, needs to choose differentiated prices. The monopoly environment analyzed in single-period two-period (with invariable market then variable market) planning horizons, optimal pricing strategy for characterized. results of horizon show that remanufactured not only grab some share from ones form “bank run” but also maintain...
Remanufacturing, which processes end-of-life products with disassembly, testing, reprocessing, and reassembly operations in such a way that their quality performance is restored, has attracted substantial interest recent years. In this article, we address capacitated dynamic lot-sizing problem remanufacturing, there are heterogeneous demand streams for newly manufactured assembled wholly by brand-new components remanufactured ones reassembled reprocessed components. The could also be...
In order to solve the nonlinear integral difficulty of Mises yield criterion, a linear called collaborative approximation (CA) is proposed by control method. According method, mathematical expression CA criterion derived as function three principal stresses. The theoretical results based on in form Lode parameter are verified with classical test data, and good agreement found. Meanwhile, for purpose proving effectiveness its specific plastic power applied establish rolling force model an...
A frequency selective absorber for harmonic absorption (HA-FSR) is proposed in this paper.It consists of a miniaturized surface (FSS) suppression and circuit analog (CAA) absorption.The rasorber (FSR) unit 6.7 mm × (0.129λ 0.129λ, where λ the free space wavelength 5.8 GHz).The simulation measurement show that HA-FSR can generate transmission band from 4.51 GHz to 7.47 -10 dB 11.96 22.31 GHz, which covers more than 3 times main passband band.In addition, FSR has good polarization stability...
Aeroelastic response of gust is always an important problem in flight quality assessment.In this study, structure and aerodynamic solvers based on Lagrange equation Euler are coupled with loose coupling method.Elastic general-purpose airplane a high-aspect-ratio transport elastic wings simulated.The simulations proved the capacity method studied dynamic different conditions.
