Fault Detection of a Roller-Bearing System through the EMD of a Wavelet Denoised Signal

This paper investigates fault detection of a roller bearing system using a wavelet denoising scheme and proper orthogonal value (POV) of an intrinsic mode function (IMF) covariance matrix. The IMF of the bearing vibration signal is obtained through empirical mode decomposition (EMD). The signal screening process in the wavelet domain eliminates noise-corrupted portions that may lead to inaccura...

Neutron Diffraction Measurements on a Large Size Roller Bearing

In common with many engineering applications the introduction of compressive surface stresses plays an important role in the performance of roller bearings. Since the introduced stress profiles depend on the treatment method and the necessary balancing tensile stresses may have unexpected consequences, it is necessary to quantify the stresses throughout the bearing. Today, most characterization...

Extracorporeal tubing in the roller pump raceway: physical changes and particulate generation.

Plasticized polyvinyl chloride tubing is used as the blood conduit in the heart lung bypass circuit. The section in the roller pump undergoes rigorous compression. Fatigue leads to material changes in weight and length of the bulk material. Particles are released during normal pump operation. This study evaluates the time course of particle loss. Three segments of 1/2" ID tubing run in the race...
