The researchers, studied natural frequency and deformation analysis of a step-turned machine shaft using finite element method. The step- turned machine shaft was modeled with inventor, having an assigned material being Austenitic Stainless Steel to reduce deformation and corrosion. The solid cylindrical shaft retained variable cross sectional diameter of 30mm and 50mm with length of 50mm each. Modeled shaft was imported into Finite Element Analysis Software where deformation was analyzed. In addition, turning moment of 400 N mm and bearing load of 1200N were adopted with fixed constraints. Results from the analysis revealed that the natural frequency was found to be 9801.78 Hz with maximum deformation of 6. 124 mm. Also, the general design information and mechanical properties of the machine shaft were discovered from the study. To avoid failure, the frequency of the periodic external load the shaft would be subjected to must be lower than 490.089Hz and 1200N in line with the given conditions. The researchers made the following recommendations: Machine shaft material must have higher natural frequency greater than periodic load frequency, to avoid failure due to resonance; this research can also be done in future using different shaft geometrical designs such as spindle shaft, square shaft, hollow shaft and other advanced software in computer aided engineering for generalization, etc.
