2019-7-1Slewing bearings are critical functional components of large machinery and their residual useful life (RUL) prediction can avoid downtime and reduce accidents and casualties In the field of their condition monitoring and life prediction multi-signal and multi-feature fusion (MSMFF) is a trend for over the current literatures
2020-1-2The monitoring data of slewing bearing is massive In order to establish accurate life prediction model from complex vibration signal of slewing bearing a life prediction method based on manifold learning and fuzzy support vector regression (SVR) is proposed Firstly the multiple features are extracted from time domain and time-frequency domain
Reliability and safety are major issues in tower crane applications A new adaptive neurofuzzy system is developed in this work for real-time health condition monitoring of tower cranes especially for hoist gearboxes Vibration signals are measured using a wireless smart sensor system Fault detection is performed gear-by-gear in the gearbox

This paper presents an application of multivariate state estimation technique (MSET) sequential probability ratio test (SPRT) and kernel regression for low speed slew bearing condition monitoring and prognosis The method is applied in two steps Step (1) is the detection of the incipient slew bearing defect In this step combined MSET and SPRT is used with circular-domain kurtosis time
Aiming at reducing the production downtime and maintenance cost prognostics and health management (PHM) of rotating machinery often includes the remaining useful life (RUL) prediction of bearings In this paper a method combining the generalized Weibull failure rate function (WFRF) and radial basis function (RBF) neural network is developed to deal with the RUL prediction of bearings
