Abstract

This paper presents a peak-valley segmentation procedure for the wavelet-based extraction of acceleration data. A 60-second acceleration signal was measured on a McPherson frontal coil spring of a 2000 cc Proton sedan car, and the data was used for the simulation. The Morlet wavelet-based analysis was used to extract higher amplitude segments in order to produce a shortened signal that has an equivalent behaviour. Using this process, it has been found that the Morlet wavelet was able to summarise the original data up to 49.45% with less than 10% difference with respect to statistical parameters. This clearly indicates that the Morlet wavelet can be successfully applied to compress the original signal without changing the main history as well. Finally, it has been proven that the Morlet wavelet successfully identified the higher amplitudes in the acceleration data.
