ABSTRACT The Intake manifold is considered a crucial part of the IC engine as it increases engine efficiency and performance. This is achieved through the combustion of proper fuel-air mixture intake, which is dependent on the material geometry of the intake manifold. The present work focuses on the geometrical modeling and structural analysis of the intake manifold followed by modal analysis. Static structural linear analysis was undertaken to check the structural safety using Finite Element Analysis (FEA) software. The static analysis results indicate that the equivalent stress of 426.38 MPa, maximum and minimum stress of 498.7 MPa, and 53.47 MPa respectively were induced within the component. Whereas, a minimum deformation of 56.34 mm for a frequency of 977.45 Hz and maximum deformation of 104.22 mm at a higher frequency of 2518.1 Hz were observed by modal analysis. The above numerical modeling results indicate the vibration adequacy of the intake manifold structure.
