Abstract

In this project, I'm going to do the Finite Element Stress Analysis on Natural Gas Motorcycle Intake Manifold. When a group of designer do a structural design on a machine that made of several parts, it is important to do the stress analysis on part of the design process. This is in order to optimize the structural design to meet multidisciplinary performance requirements. The purpose of this final year project is to determine Von Mises stress that will acts on the intake manifold on the natural gas motorcycle by using finite element model analysis. When a motorcycle engine running, the unbalance condition of the engine causes vibration and it will transmitted to intake manifold. This vibration will causes stress on the intake manifold. Since I do not have the real part of the intake manifold that exist in this world, hence I'm using the software called SOLIDWORKS in order to draw the intake manifold with the real life part specification as a substitute. In this study, I will do an analysis both on intake manifold with and without rib. During simulation, I will apply different material and value of pressure on both the intake manifold to gain more wide range of data to analyze. After that, from the results that I gained from the simulation, I will group together the data gain and plot graph. Finally, there is where discussion is being done and I will conclude the result for this project. It is found that by adding stiffened rib to the intake manifold helps to strengthen the manifold structure and hence it will reduce the Von Mises stress in the intake manifold depending on the material used to make the intake manifold.
