The Harmonic Response Analysis of Engine Block Based on Modal Analysis

Abstract:

The modal analysis of the engine block is carried out using finite element method. Through the analysis, the inherent frequencies and mode shapes of the first 6 order modes are obtained respectively. Then the harmonic response analysis of the engine block is carried out based on the modal analysis, and the corresponding inherent frequencies of the weak positions of block under the action of external cycle force are obtained. Finally, the consistency of the typical mode shape and amplitude-frequency curve is compared.
