Vibrational Analysis of Aluminium Graphite Metal Matrix Composite

Abstract

Abstact-In the present work analytical and experimental solutions of frequency characteristics for the vibration of isotropic metal matrix composite have been obtained. The variations in the fundamental frequency of Aluminium Graphite specimen due to its geometrical structures, percentage of graphite and material properties are going to be studied. The results are validated by the results with those available in the literature. The vibrational study started by determining of its length, thickness, weight and volume to find its density and finding an young's modulus by rule of mixtures. In experimental method is used to evaluate the first three natural frequencies and finding its modal damping from the experimental values, by using FFT analyzer by adopting all varied parameters. In analytical method determination of natural frequencies using ANSYS 11, obtaining its modal and transient analysis for all the specimens and damping ratio by using transient results.
