Durability Analysis of Motorcycle Frame Using Fatigue I-Kaz Technique

This paper presents durability analysis using a new statistical-based method, called the Fatigue Integrated Kurtosis-based Algorithm for Z-notch filter (Fatigue I-kaz) technique. This method provides a three dimensional graphical representation of the data distribution of the signal at three different frequency range in order to measure the degree of data scattering. For validation, three road surfaces were used for data collection purposes. An experiment has been performed on the motorcycle frame. In this study, the strain signals were collected based on three different road surfaces. The strain gauges were fixed on the motorcycle frame to measure the variable strain amplitude loadings imposed. The strain signals were then analysed using Fatigue I-kaz coefficient. Residential road surfaces give a higher Fatigue I-kaz coefficient, f than campus and off road surfaces which is 0.0120 which is 0.0079 and 0.0067
