Abstract: Gearbox casing is the main component in automobile world which is used to protect components inside the gearbox. It consists of gears, shafts, bearings and oil. It is fluid containing casing which gives support to the moving parts. Gearbox failure occurs mainly due to the design issues, manufacturing defects, oil deficiency, excessive time at stoppage and high loading. In this project loading case is considered. Major challenge for such problems are whether to consider static analysis, dynamic analysis, or perturbation analysis and conditional circumstances for it to be performed. In this work static dynamic as well as perturbation analysis have been performed on gearbox casing. Model is to be developed in Abaqus/CAE and then same model is used for Finite Element Analysis by using Abaqus/Standard 6.10.1 for static analysis and dynamic analysis. Harmonic analysis is also performed by Abaqus software called as perturbation analysis for strain and frequency. Stress and frequency graph in both the cases that is in static and dynamic analysis is performed and results from static and dynamic are compared. Frequency effect on strain levels are linear and no surplus strain linearity is produced due to dynamic effect as compared to the static case. By using Abaqus/ standard it is found that results boost for dynamic case as compared to static case.
