| Abstract: | Cylinder block, framework of a diesel engine suffered complicated forces on running condition. 3- D geometry of 4120SG diesel engine block is built by PROE. Structural elements and nodes of block are processed and created by the software MSC. GSMESHER. Various excitation forces, such as combustion pulse, main-bearing load and piston side-thrust, are calculated and applied to the engine system model to predict the transient vibration response of running engine by Finite Element Method. Comparisons are made between vibration measurements and calculated one. The results show the accuracy of the calculation. |
