Statistical multivariate monitoring of rolling bearings working under varying operational conditions

Autor: Baoxiang Wang, Hongxia Pan

Publikováno v: IET Science, Measurement & Technology, Vol 15, Iss 9, Pp 749-762 (2021)

Abstract In recent years, statistical data‐driven approaches have been developed for health monitoring of rolling bearings working under variable operational conditions. Due to the reliance on reference models, most of them encounter with the model

A TEO‐based modified Laplacian of Gaussian filter to detect faults in rolling element bearing for variable rotational speed machine

Autor: Yi Liu, Zhansi Jiang, Haizhou Huang, Jiawei Xiang

Publikováno v: IET Science, Measurement & Technology, Vol 15, Iss 2, Pp 193-203 (2021)

Abstract Conventional signal processing techniques for fault detection are usually aimed at constant speed conditions. Nowadays, order tracking, especially tacho‐less order tracking is regarded as a valuable tool for extracting fault features under

Fuzzy criticality assessment for process equipments maintenance

Autor: Qi, Hong Sheng, Liu, Q., Wood, Alastair S., Alzaabi, R.N.

Criticality-based maintenance (CBM) is a prioritized approach to the maintenance of (industrial) process equipment. CBM requires personnel with a thorough knowledge of the process/equipment under scrutiny. In this paper a criticality assessment syste
