| Abstract: | In this paper, a cylinder block of YC4108Q diesel engine is studied. By experimental modal analysis,the mode shapes and natural frequency of the cylinder block are obtained.Then based on the test data, and using 3-D CAD software UG and structure analysis software MSC. NASTRAN, a 3-D FEA dynamic model of cylinder block is built and analyzed. Finally, the best improvement scheme for the structure of cylinder block is obtained based on the analysis results. |
