The method of quality monitor based on wavelet filtering was proposed to solve the problems of quality control in multi-operation manufacturing processes, whose measurement data contained noise information. The multi-operation machining process quality control model based on the Stream of Variation (SoV) technology was built, which considered the error propagation. Based on this, the method of discrete...
This paper provides a vibration-based diagnostic platform to systematically monitor and diagnose of rotary machine faults. Commonly rotary machine faults described in this paper are misalignment fault, bearing cage defect, ball bearing defect, bearing outer race fault and inner race fault. The use of structural resonance frequency, ISO 10816 for vibration level assessment, spectrum assessment for...
