Executive Summary

The project is Wavelet Based Vibration Analysis of Test / Post Flight Vibration / Acoustic Data.  Unlike the traditional vibration analysis, which is based on Fourier methods, the current project aims to extract more information (from both temporal and frequency domain simultaneously) by using the relatively recent wavelet analysis. The objective of the project is to conduct thorough investigations to identify good wavelet-based features and support vector machine based classification algorithms to characterize the vibration signatures.  Using the extracted wavelet based features as inputs, support vector machines (SVM) is used to classify and predict the various faults occurring in the mechanical system
