FMEA—A diagraph and matrix approach
This paper presents a method for failure mode and effects analysis (FMEA) of mechanical and hydraulic systems based on a diagraph and matrix approach. The method takes into account structural as well as functional interaction ...
Comparison of vibration and acoustic measurement techniques for the condition monitoring of rolling element bearings
The detectability of defects in ball bearings by various vibration and acoustic measurement methods is compared. Measurements have been performed on good new bearings and bearings with simulated defects in their elements. ...
Distortion analysis of large thrust bearing on elastic support
A model for the analysis of distortion of a large thrust bearing pad is proposed. The analysis aims to simulate the realistic conditions in bearings. Free-edge boundary conditions are implemented and spring-supported pads ...
A comparison of some vibration parameters for the condition monitoring of rolling element bearings
In the present study some of the vibration parameters used for the detection of defects in rolling element bearings have been compared. Overall RMS, peak, crest factor, power and cepstrum of the vibration acceleration ...
Environmental studies of SO2, SPM and NOx, over agra, with various methods of treating calms
A comparative study between predicted and observed concentrations of major pollutants SO2, suspended particulate matter (SPM) and NOx in Agra, India has been undertaken using two Gaussian plume models. A Gaussian plume ...
