ABSTRACT
Engine pistons are one of the most complex components in the automobiles. The Engine can be called as heart of the Automobile and Piston may be considered as vital part of the Engine. There were lots of research works progresses for Engine piston and for new geometries in manufacturing methods and assessment, as piston exposes to high temperatures and maximum stresses. An attempt is made in this paper to carryout static analysis of Four Stroke Gasoline Engine piston by Using different materials such as Aluminum Alloy (AA2618), Steel Alloy (AISI4340) and Titanium Alloy (Ti-6Al-4V). The dimensions of the piston are 80mm in diameter, 80mm in length, Top land width of 8mm, two compression rings of thickness 2.5mm and 2.5mm and Oil ring thickness of 5mm. First the piston is modeled by using CATIA V5 software, then meshing and analysis is done by ABAQUS CAE Software by using FE Analysis. The static analysis is done by applying different pressures 5MPa, 10MPa and 15MPa for different materials. The results are drawn for the different pressures of piston contour of von-misses stresses and displacements for Aluminum Alloy AA2618, Steel Alloy AISI 4340 and Titanium Alloy Ti-6M-4V. Further it is observed that Aluminum Alloy AA2618 at different pressures of 5MPa, 10MPa and 15MPa maximum Von-misses stress are 230.504MPa, 461.222MPa and 692.158MPa then displacements are 0.072mm, 0.144mm and 0.217mm respectively. Similarly for Steel Alloy AISI 4340 at different pressures of 5MPa,10MPa and 15MPa, maximum Von-misses stresses are 241.74MPa, 463.563MPa and 695.446MPa then displacements are 0.027mm, 0.055mm and 0.082mm respectively and for Titanium Alloy Ti-6Al-4V at different pressures of 5MPa,10MPa and 15MPa maximum von-misses stresses are 228.89MPa, 457.897MPa and 694.463MPa then displacements are 0.050mm, 0.101mm and 0.135mm respectively. From the above results, it is observed that the best material for static analysis is Steel Alloy AISI 4340.
