Study on the Instrument Panel Assembly Modal Analysis Basic on CAE Technology

摘要

Modal performance of the automotive instrument panel has been studied in this article. Finite element software Hypersh/OptiStruct has been used in modal analysis in this article. This paper first calculated the modal frequency and vibration shape of the instrument panel. Engineered modification has been applied to rise the inherent frequency. The result shows this method can effectively optimize the inherent frequency of the instrument panel assembly.
