Abstract

AISI 1045 steel is used extensively by most industry sectors mainly in automotive for applications requiring more strength and wear resistance such as connecting rods. Connecting rods are widely used in variety of car engines. It is subjected to forces generated by mass and fuel combustion, thus, it must be capable to transmitting axial tension and compression. In this paper, connecting rod was used as a research material. This article discusses the analysis on strain signal of fatigued material using a new method called Integrated Kurtosis-based Algorithm for Zfilter (I-kaz) approach. Fatigue tests were performed according to the ASTM E466-96 standard with the attachment of astrain gauge to the tested specimen. Fatigue test was carried out using variable amplitude loading (VAL) at frequency 8 Hz. A data acquisition system was used to collect those fatigue strain signals. Fatigue damage characteristics were observed through the signals and analysis was performed by using I-kaz approach. I-kaz parameter was determined to relate with fatigue failure assessment which will describe the fatigue life.
