| 2 | Vibration-based synchronous sampling and its application in wind-turbine drive-train-condition monitoring显示文摘Utilizing shaft-speed information to analyse vibration signals is an important method for fault diagnosis and condition monitoring of rotating machineries,especially for those running at variable speeds.However,in many cases,shaft-speed information is not always available,for a variety of reasons.Fortunately,in most of the measurements,the shaft-speed information is embedded in the vibration response in many different forms,such as in the format of the fundamental shaft-rotation-frequency response and its harmonics,and the gear-meshing-frequency response and its harmonics,etc.Proper signal processing can be used to extract the shaft instantaneous speed from the measured vibration responses.In existing instantaneous shaft-speed-identification methods,a narrow-bandpass filtering technique is used explicitly or implicitly.In a complex gearbox system,such as that used in a wind turbine,the gear-meshing-response component could be modulated by many other shaft speeds,due to the configuration of the gearbox or due to the existence of component damage.As a result,it is very difficult to isolate a single vibration-response component for instantaneous shaft-speed detection.In this paper,an innovative approach is presented.The instantaneous shaft speed is extracted based on maxima tracking from the vibration-response spectrogram.A numerical integration scheme is employed to obtain the shaft instantaneous phase.Digital-domain synchronous resampling is then applied to the vibration data by using the instantaneous phase information.Due to the nature of noise suppression in the numerical integration,the accuracy of synchronous sampling is greatly improved.This proposed approach demonstrates the feasibility and engineering applicability through a controlled laboratory test case and two field wind-turbine cases.More detailed results and conclusions of this research are presented at the end of this paper. | Ting Hu Hongyi Wan Huageng Luo | 2021 | Clean Energy2021，5，1： | 1 |
| 3 | Heterogeneous optomechanical crystal cavity coupled by a wavelength-scale mechanical waveguide显示文摘Integrated optomechanical crystal(OMC)cavities provide a vital device prototype for highly efficient microwave to optical conversion in quantum information processing.In this work,we propose a novel heterogeneous OMC cavity consisting of a thin-film lithium niobate(TFLN)slab and chalcogenide(ChG)photonic crystal nanobeam coupled by a wavelength-scale mechanical waveguide.The optomechanical coupling rate of the heterogeneous OMC cavity is optimized up to 340 kHz at 1.1197 GHz.Combined with phononic band and power decomposition,17.38%energy from the loaded RF power is converted into dominant fundamental horizontal shear mode(SH0)in the narrow LN mechanical waveguide.Based on this fraction,as a result,3.51%power relative to the loaded RF energy is scattered into the fundamental longitudinal mode(L0)facing the TFLN-ChG heterogeneous waveguide.The acoustic breathing mode of the heterogeneous OMC is successfully excited under the driving of the propagating L0 mode in the heterogeneous waveguide,demonstrating the great potentials of the heterogeneous piezo-optomechanical transducer in high-performance photon–phonon interaction fields. | YANG LUO HONGYI HUANG LEI WAN WEIPING LIU ZHAOHUI LI | 2023 | Photonics Research2023，11，9： | 0 |
