A weak fault feature extraction of rolling element

The time domain signal of bearing pitting/spalling fault always presents shock and modulation and it is often submerged by strong noises especially in the early stage the conventional fault feature extraction method may have insufficient feature extraction accuracy and even in some extreme cases the fault feature frequency cannot be extracted because of the strong noise interference

Machine

2020-8-13A machine (or mechanical device) is a mechanical structure that uses power to apply forces and control movement to perform an intended action Machines can be driven by animals and people by natural forces such as wind and water and by chemical thermal or electrical power and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces

transverse structure

The invention relates to an element for routing cables comprising a load-bearing rigid structure that includes longitudinal structural elements (12 13 12' 13') made of electrically insulating plastic or composite material and transverse structural elements (11 21 51 52) connecting the longitudinal structural elements

Adaptive online dictionary learning for bearing fault

One of the most common parts to maintain system balance and support the various load in rotating machinery is the rolling element bearing The breakdown of the element in bearings leads to inefficiency and sometimes catastrophic events across various industries The main challenge over the last few years for fault diagnosis of bearings is the early detection of fault signature

A dictionary learning approach to monitoring of wind

Rolling element bearings are essential components of rotating machines which are particularly important to monitor due to the high requirements on the operational conditions Bearings are also located near the rotating parts of the machines and thereby the signal sources that characterize faults and abnormal operational conditions

Numerical simulation and experimental

In an industrial context bearing failure can have costly consequences This paper presents a study of the rolling contact fatigue damage applied to thrust ball bearings It consists in building a dynamic three-dimensional numerical model of the cyclic shift of a ball on an indented rolling surface using finite element analysis (FEA)
