Fault feature extraction of planet gear in wind turbine gearbox based on spectral kurtosis and time wavelet

Yun KONG, Tianyang WANG, Zheng LI, Fulei CHU

Frontiers of Mechanical Engineering 2017, Volume 12, Issue 3, Pages 406-419 doi: 10.1007/s11465-017-0419-0

Abstract: time-variant vibration transfer path, and heavy background noise masking effect, the vibration signal of planetimpulsive components induced by a localized defect are hard to extract, and the fault detection of planetAiming to extract the fault feature of planet gear effectively, we propose a novel feature extractiondemonstrate that the proposed method is effective at the feature extraction and fault diagnosis for the planet

Multi-objective genetic algorithms based structural optimization and experimental investigation of the planet

Pengxing YI,Lijian DONG,Tielin SHI

Frontiers of Mechanical Engineering 2014, Volume 9, Issue 4, Pages 354-367 doi: 10.1007/s11465-014-0319-5

Abstract:

To improve the dynamic performance and reduce the weight of the planet carrier in wind turbine gearboxFirstly, the design points’ distribution for the design variables of the planet carrier is establishedAs well, this method is applied to design and optimize the planet carrier in a 1.5 MW wind turbine gearboxCompared with the original design, the mass and the stress of the optimized planet carrier are respectivelyConsequently, the cost of planet carrier is greatly reduced and its stability is also improved.

Managing soil quality for humanity and the planet

Rattan LAL

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 3, Pages 251-253 doi: 10.15302/J-FASE-2020329

Abstract:

Rather than a human-centric, the basic strategy of achieving Sustainable Development Goals must be focused on restoring and sustaining planetary processes. The urgency of meeting the demands of the humanity must be reconciled with the necessity of enhancing the environment. Increasing and restoring soil organic matter content of the degraded and depleted soils is critical to strengthening planetary processes.
