Acoustic Analysis of an Exhaust MANIFOLD by INDIRECT Boundary Element Method

Acoustic Analysis of an Exhaust MANIFOLD by INDIRECT Boundary Element Method

The present work is aimed at the development of a numerical procedure, based on the usage of the Boundary Element Method (BEM) as implemented in the software LMS Virtual.Lab, for the vibro-acoustics analysis of an exhaust manifold. The manifold vibrations are induced by two different ways: engine vibrations (transmitted to the manifold surfaces) and turbulences generated by the air flow in the ...

Experimental and finite element vibrational analysis of exhaust manifold heat shield

Most of internal combustion engines have one or two heat shields that have been installed on the exhaust manifold to avoid the heat transfer to upper parts of the engine such as the valve cover. In some engines, this part fails due to the fracture and causes engine noise and other failures in the engine. In this paper, the failure of a heat shield due to vibrational loads of the engine has been...
