Tacho-less

A tacho-less processing is required, which can automatically detect bearing defects at varying speeds. In varying speed data, amplitude and time interval amongst the impulses are varying. Also, the defect information is hidden in noise and crossing harmonics. WebThe generalized demodulation based tacho-less order tracking is a promising gear fault diagnosis method due to its being applicable to large rotational speed variation condition (larger than ±30%) and its good robustness to noises. However, the current single-stage generalized demodulation based tacho-less order tacking is insufficient for ...
