dc.description.abstract | This paper presents the analysis on variable amplitude
(VA) loading strains data using cross correlation function
(CCF). CCF is a method to measure a similarity of two
fatigue time series as a function of a time-lag applied to
one of them. Cross correlation is generally used when
measuring information between two different time series.
The objective of this study is to observe the capability of
this method in detecting the similarity of signal pattern
between two critical stress points, a set of case study data
consist of nonstationary VA loading strains data that
exhibits a random behaviour was used. This random data
was collected in the unit of microstrain on the lower
suspension arm of a mid-sized sedan car. The data was
repetitively measured for 60 seconds at the sampling rate
of 500 Hz, which gave 30,000 discrete data points,
travelling on a pave road and highway route. The
collected data was then calculated and analysed using
CCF. Higher calculated cross correlation coefficient
value was then selected to analyse the fatigue analysis for
further study. | en_US |
