| Abstract: | Design parameter modifying method"of modifying finite element model by modal analysis result is introduced briefly in this paper. It is validated by the cylinder head of a heavy duty diesel as a sample. The calculation and analysis result show that the finite element model modified by this method is able to reflect the structural dynamic characteristics accurately and that this method possesses rather reliability. |
