Knowledge Discovery from Vibration Measurements
The framework as well as the particular algorithms of pattern recognition process is widely adopted in structural health monitoring (SHM). However, as a part of the overall process of knowledge discovery from data bases (KDD), the results of pattern recognition are only changes and patterns of changes of data features. In this paper, based on the similarity between KDD and SHM and considering t...
متن کاملVibration Analysis of Refrigerant Compressor Shaft
An analysis of transverse vibrations of a compressor, using the modified Mykle stad-Prohl method which is one of the transfer matrix methods, is explained. A 10 hp four-cylinder refrigerant compressor was used as an object. The shaft and the frame are modeled as beams which are coupled with the sets of a spring and a damper that are the models of bearing oil film, bearing pedestals or the magne...
متن کاملShaft Misalignment and Vibration - A Model
Misalignment of coupled rotating machinery shafts is a frequently occurring problem which can have a substantial influence on equipment reliability. Experience has shown that diagnosis of misalignment through vibration analysis can be extremely difficult due in large part to the observed substantial variability in the character of machinery vibration even when apparently identical alignment sta...
متن کاملSetting Limits
The ability to perceive the chemical world is a universal feature of life. In mammals, the olfactory system detects and discriminates between vast numbers of distinct volatile molecules (recently estimated at an astonishing > 1012 in humans) providing critical information that allows an organism to respond appropriately to changes in its environment. The universe of volatile odorants is accommo...
متن کاملBlade and Shaft Crack Detection Using Torsional Vibration Measurements Part 3: Field Application Demonstrations
The primary goal of the this paper is to summarize field demonstrations of the feasibility of detecting changes in blade and shaft natural frequencies (such as those associated with a blade or shaft crack) on operating machinery using non-contact, nonintrusive measurement methods. Laboratory demonstration of feasibility and some special signal processing issues were addressed in Parts 1 and 2 [...
