Abstract
Based on the combination of modal analysis technology and finite element method (FEM), the modal parameters identification of the main parts of a diesel engine (crankshaft ,connecting rod and oil pan) were tested using hammer beat method and calculated by means of I-DEAS software. The natural frequency and shake mode parameters of the parts were identified. The results could provide basis for structure dynamic analysis and control of noise of the diesel engine.
