A comparison of some condition monitoring techniques for the detection of defect in induction motor ball bearings

A Comparative Study between Vibration and Acoustic Signals in HTC Cooling Pump and Chilling Pump

“…Chilling Pump this frequency can be intended knowing the geometry of the bearing and its revolving speed, Usually these frequency lie in the low-frequency range (less than 500Hz) [7,8].The existence of a fault in industrial utensils will be accompanied by a noticeable increase or modification of vibratory signal [9,10] …”

A new methodology for fault detection in rolling element bearings using singular spectrum analysis

“…There are several studies that focus on reviewing and comparing the performance of some of the approaches for the health monitoring of rolling element bearings [1][2][3][4][5] . Due to the complexity of the bearing vibration signal resulting from factors such as clearance and friction, some of these approaches are complex in structure but perform well in fault detection.…”

Inspection optimization model with imperfect maintenance based on a three-stage failure process

“…SPM, developed by SPM instrument AB Company in the early 1970s and originated in Sweden, is a patented technique and has achieved wide acceptance as a quantitative method for efficiently inspecting the condition of bearings [6,12]. Through sampling the shock pulse amplitude of bearings over a period of time and displaying the maximum value dB m and the carpet value dB c , SPM provides a direct normalized shock value indicating the bearing operating state and lubrication condition [7].…”
