Statistical Analysis of Free Vibration Response of Aluminium Matrix Composite Plate manufactured by Stir Casting Process by using Taguchi Method

Abstract

Composite material is a combination of two or more materials having compositional variations and depicting properties distinctively different from those of the individual materials of the composite. Aluminum hybrid reinforcement technology is a response to the dynamic ever increasing service requirements of such industries as transportation, aerospace, automobile, marine, etc. Manufacturing of aluminum alloy-based casting composite by stir casting is one of the most economical methods of processing MMC. Composite material is manufactured by reinforcing A356 alloy with Al2O3 and fly ash particles. Analysis is done to study the vibration response characteristics i.e. natural frequency and amplitude of composite plates to find effect of various parameters on these response characteristics. By using MINITAB software, results are computed and statistical data is presented to determine the influence of input parameters on vibration response.
