Data on Mathematics Reported by Researchers at Army Engineering University (Research On the Health Status Evaluation Method of Rolling Bearing Based On Emd-ga-bp)

摘要

By a News Reporter-Staff News Editor at Network Daily News – Current studyresults on Mathematics have been published. According to news reporting originating in Shijiazhuang,People’s Republic of China, by NewsRx journalists, research stated, “To more accurately evaluate thehealth state of rolling bearings, this paper proposes a health status evaluation method based on empiricalpattern decomposition, genetic algorithm and BP neural network. Firstly, the vibration signal is decomposedby empirical mode decomposition (EMD) and the time domain features of each intrinsic mode function(IMF) component are extracted, and the signal-to-noise ratio (Snr) of the signal is improved effectively.”
