摘  要:
The dynamic characteristic analysis for cylinder block of S195 diesel engine is performed by use of dynamic finite element and experimental modal analysis. The results about natural frequency and modal shape in the finite element analysis and modal analysis are almost equal. Through deformation data analysis of forced response simulation on the block struction the trouble mechanism is found. The results show that predicting the dynamic characteristic and deformation by finite element analysis is re liable and efficient.
