Abstract
In this study, the configurations of the two engine exhaust manifolds were designed. And the strengths and durabilities were analyzed through the structural analysis and natural frequency analyses of these models. As the result of structural analysis, the strength of model A is much better than that of model B because the maximum stress and deformation of model B are considerably greater than those of model A by more than 9 and 39 times, respectively. It can also be confirmed that model A has the durability better than model B because the maximum frequency of model A is greater than the natural frequency of model B and its maximum deformation is smaller than model B. The result of this study can be used to investigate the durability due to the exhaust manifold shape of medium-sized car without actual test. It also seems to be helpful in the aesthetic convergent design of small car muffler.
