Static and Thermal Analysis of a Piston with Different Thermal Barrier Coatings

Atthuru Kalyan, Dr. D. R. Srinivasan

Abstract: The design of engine pistons is one of the most complicated in automobile engines it is subjected to extremely high temperatures and high pressures resulting in high thermal stresses and thermal strains. Several investigators had carried out different research works wherein some of them addressed this issue by proposing new geometrical shapes of the piston and some others stressed the use of new materials like various alloys to ensure that their pistons meet the design requirements following operating performance improved during the engine operation in the present work both experimental &numerical investigation has been carried out on piston i.e. static analysis and thermal analysis on a 4-stoke gasoline engine piston using various metals used for construction manufacture of the piston such as aluminum -silica alloy and (AA4032) the piston was modeled using CATIA V5 R20soft ware followed by meshing and analysis with the help of ABAQUS CAE software. The static analysis was carried out by applying different static loads i.e., 2mpa and 4mpa to predict and evaluate deformation and stresses. The thermal analysis was also carried out. The results obtained for the above analysis were stress distribution, displacement distribution, and temperature distribution contours from their results it was observed the best material is AA4032 as it is found to have the lowest deformation at all pressures as improved temperature distribution and also the life of piston used for gasoline engine higher as observed comparatively static and thermal conditions for thermal barrier coated piston and then normal piston .when also tested as well as practical applications in the hero 100cc bike engine.
