ABSTRACT The study of a jet engine mounts by FEA usually deals with the stress analysis of the mount, a very few papers deal with the displacement analysis. It is futile to believe that mounts that only stress analysis is necessary, as the displacement of the mount(elongation) is also an important factor when real life scenarios come into play.For the study the mount was designed using CATIA V5 and was analyzed using ANSYS. The ends that were to be fixed onto the chassis were fixed and then suitable load of 1000[4]N was applied to the load bearing region. Study was initially done using Al alloyand Mg as materials and then titanium alloy(Ti 6Al 4V) was also used on the final model.The initial models had a stress in the range of 10 and displacement was in the range of 20-30 meters which was unacceptable and suitable modification were made to the model in geometry and its dimensions so as to reach the optimal value of 5 mm displacement and stress of 2.5 KN for Al and 10 mm displacement and 3 KN stress for Mg alloy. Later the study was done using Titanium alloy(Ti 6Al 4V) and it is seen that the stresses and displacement were well within the permissible limit.From the study it is very evident that of all materials Titanium alloy had the minimal deviation from ideal behavior, and it is safe to assume that Titanium alloy(Ti 6Al 4V) is the most suited alloy to make engine mounts.
