ABSTRACT
The finite element analysis of the effect of vibration on a generator cylinder block using a modal analysis has been successfully carried out in this study. The generator cylinder block was singled out for its importance in the internal combustion engine system. The component is the basic structure in the engine system. The component was graphically modeled in the AutoCAD software and exported to the ANSYS environment for analysis. The Modal analysis tool was applied in the analysis. The component was meshed and attached with boundary conditions. The maximum equivalent stress, equivalent strain and total deformation of the engine component were determined to be 25.656 MPa, 0.000132, and 1.1064 mm respectively at a vibration frequency of 60.439 Hz. The effect of the vibration on the engine component reveals that a maximum and minimum total deformation of 1.1064 mm and 0.11239 mm respectively occurred at a frequency of 60.465 Hz . Also, it was noticed that the maximum and minimum total deformation increased to 1.6529 mm and 0.18066 mm respectively at a frequency of 65.211 Hz. It is a pointer that the higher the frequency the higher the rate of deformation, stress impact and vibration.
