WebThe fault feature of wind turbine bearing is usually very weak in the early injury stage, in order to accurately identify the defect location, an original approach based on optimized cyclostationary blind deconvolution (OCYCBD) and singular value decomposition denoising (SVDD) is put forward to extract and enhance the fault feature effectively. In …
WebFeb 27, 2024 · Blind deconvolution (BD) is a well-established sparse feature enhancement method for the diagnostics of rolling bearings. Traditional BD methods, such as minimum entropy deconvolution (MED), are susceptible to random transients, making it difficult to enhance fault features of rolling bearings subject to strong random shocks. the mandalorian 3d printWebFeb 1, 2024 · Generally, deconvolution methods have three typical forms: non-blind deconvolution (NBD) method, blind deconvolution (BD) method and semi-blind deconvolution (BD) method.
