      In automotive engineering, an intake manifold or inlet manifold is the part of an engine that supplies the fuel/air mixture to the cylinders.

This project focused on simulation testing of automotive intake manifold design using computer aided engineering software. Finite element random vibration analysis is conducted on excavator intake manifolds designs for material cast iron and aluminium alloy. The purpose of this project is to study the computational maximum stress on the model due to the effect of engine vibrations and pressure pulsation loads. The softwares used are PRO-E 4.0, HYPERMESH-10 and ANSYS-11. Based on the simulation results obtained, the maximum stress of both materials is compared to distinguish which is better in resisting the vibration loads applied.
