Noise radiation analysis of an engine's component can be implemented
through several methods such as theoretical calculations, experimental and
simulation. The use of finite element method integrated with boundary element
method based computer software in engineering field has shown growing interest due
to shorter duration of analysis and easy to use. In this analysis, observation of
vibration characteristic for two-stroke engine's cylinder head is carried out. Initially,
finite elements are used to create the engine's cylinder head model. Data gained
from modal analysis is used for prediction of noise radiation from cylinder head
surfaces. At this stage, acoustic boundary element model is preferred instead of
finite element model. Finally, the results of this study can be used for further
analysis in designing of two-stroke gasoline engine
