This paper presents insights into the influence of ball size on flight characteristics and damage a bearing embedded in rear detonated cylindrical charge. It includes results from post-test analysis bearings previously reported experiments. Computational simulations using Ansys Autodyn were used to provide extra information about velocity variation during sustained by blast event. The (diameter...

Diagnostic methods including bearing problems represent one of the most important challenges. The scuffing phenomenon initiation of the bearing elements produces an important increase in the vibration level and can be emphasized by the analysis of the bearing friction forces which are the most sensitive indicator of the bearing failure. Commonly used technique for damage detection is the vibrat...

This paper uses Multi-Layer Perceptron Neural Network (MLPNN) for comparing the linear dimensionality reduction techniques (DRTs) for fault diagnosis in rolling element bearing (REB).The vibration signals from normal bearing (N), bearing with defect on ball (B), bearing with defect on inner race (IR) and bearing with defect on outer race (OR) have been acquired under different radial loads and ...
