FREQUENCY RESPONSES OF ALUMINUM A356 BASED ON HIGH STRENGTH ALLOY COMPOSITE (HSAP)

MMCs are promising materials under constant development and their application in different industries is increasing. Aluminum is one such pioneer materials which is being used extensively in aerospace, automotive and the manufacturing industry. In the present study an analysis tool finite element analysis (FEA) will be used. The work presented in this paper is aimed at the study of vibration characteristics of aluminum A356 with different reinforcements. A356 alloy and Al?20Cu?10Mg alloy system has been investigated as matrix and reinforcements. Modulus of elasticity of composites was found from tensile test, and the samples are synthesized through stir casting technique by dispersing high strength alloy particulates (HSAP) quickly and continuously to the vortex, and ingot into a Cast Iron cylindrical mould. Homogenized billets were hot extruded into ? 14 mm rod form. Density of the composites found to be increasing with increases weight ratio of reinforcements which is in tune with the calculated values by rule of mixtures, a variation densities among A356 Alloy and weight ratio (5%?10%?15%) reinforcements has been observed. Modeling of the samples using Solids Works 2013 and a modal analysis carried out using ANSYS software v.14.5, to understand the vibration behavior of the composite materials. Which play an important role in the design of dynamic machines. The harmonic analysis has done to determine the natural frequencies and the mode shapes of composite materials where evaluated and compared. The study showed that the effect of density and modulus of elasticity mainly on the vibration characteristics of the composite material where the natural frequency increases to increase the modulus of elasticity. The decrease of density causes the frequency increases of the samples, as well as the second moment of area has Influence on the vibration characteristics. The results are evident that vibration properties is higher for A356?10% in comparison with (A356 alloy, A356?5%, and A356?15%).
