TL;DR: In this paper, a modulation signal bispectrum (MSB) analysis is applied to motor current from different broken rotor bar cases and a new MSB based sideband estimator is introduced for obtaining the amplitude at ( 1 ± 2 s ) f s (s is the rotor slip and f s is the fundamental supply frequency) with high accuracy.

TL;DR: In this paper, a modulation signal bispectrum based motor current signal analysis (MSB-MCSA) is proposed for gear wear monitoring. But, the method is not suitable for the case of high gear wear.

TL;DR: In this article, the authors used dynamic time warping (DTW) to process the motor current signals for detecting and quantifying common faults in a downstream two-stage reciprocating compressor.

TL;DR: In this article, a coupled thermo-elastic 3D finite element model has been developed to analyse the frictional heat generation and transient thermal behaviour of spiral bevel gears, and the heat fluxes due to friction effects are applied to the gear tooth to investigate thermal characteristics and prediction of transient temperature fields.

TL;DR: In this paper, a gear wear condition monitoring approach based on vibration signal analysis using the modulation signal bispectrum-based sideband estimator (MSB-SE) method is presented.
