Abstract: The Cylinder Block forms the basic framework of the Engine. It houses the Engine cylinders, which serve as bearings and guides for the pistons reciprocating in them. The Engine Cylinder Block is to be carried-out to predict its behavior under Modal Analysis. The Engine Cylinder Block has to with stand the frequencies and deformations due to Modal loads acting upon it. An attempt is made in this paper to perform Modal Analysis on V-12 Engine Cylinder Block for different materials to obtain the variation of the frequency and the maximum deformations. Three-dimensional model of the V-12 Engine Cylinder Block is created using CATIA V5 R22 software and the mesh is generated by using tetragonal (TET) elements. The analysis of the Engine cylinder Block is carried-out by using different materials of Compacted Graphite Cast Iron (CGI GJV 450), Grey Cast Iron, AMC-SC1 and NASA 398 (Hypereutectic Al-Si Alloy) of ABAQUS 6.14 software for the application of Finite Element Analysis. The mechanical boundary conditions are applied to the Engine Cylinder Block. The Results are the obtained frequency of NASA 398 is very high of about 6124.9 cycles/time and that of Grey Cast Iron is very low i.e., 4428.7 cycles/time. Also the frequencies of AMC-SC1 and CGI are 5313.7 and 5391.3 cycles/time respectively under Modal Analysis. Based on the results the life of the Engine Cylinder Block is recommended the NASA 398 is more compared to other materials followed by CGI GJV450, AMC-SC1 and Grey Cast Iron. The maximum deformation produced for Grey Cast Iron and CGI GJV450 are same about 1.004 mm which is quiet nearer to the deformations produced as in the case of AMC-SC1 ad NASA 398 about 1.005 mm. So, in deformation point of view, the Modal behavior of all the materials is nearly same. Hence NASA 398 is better material for the Engine Cylinder Block.
