Finite Element Modal Analysis and Modal Test of A Diesel Engine Block

In order to solve the problem of a scientific research project, need to establish the finite element model of the body structure of a diesel engine using the ANSYS finite element analysis software, and calculating the free mode, so as to get the body structure of the low order modal frequency and modal shape. The finite element model is needed after the modal test on the structural comparison. By comparing the finite element modal analysis and test results, verify the rationality analysis model and the results of finite element mode, provide the reference for the design and optimization of this type of engine body structure.
