Free Modal Analysis of a 2-Cylinder Diesel Engine Cylinder Block
The three dimensional model of a 2-cylinder diesel engine block is established with the P ro/E software, and then the modal analysis of the engine block is carried out using finite element method with ANSYS software . Through the analysis, the inherent frequencies and mode shapes of the first 6 order modes are obtained respectively, and then are compared with the testing result; comparison shows the results of FEA estimation are in good agreement with those of testing which indicates the FEA results’ correctness. The results of the relative distribution of the vibration magnitude in the whole block are given, which provide necessary guides for the dynamic optimal design of the engine block.
