摘要:
In order to evaluate the vibration history of the engine block and predict its surface vibration status, a FEM model on 4102BZQ Diesel Engine block was constructed. Based on the cylinder pressure curve of 4102BZQ, some important exciting forces applied on the block were calculated. ANSYS software was used to compute and analyze dynamic response of the block. Simultaneously the node displacement history of the block model was obtained. The results of calculation and analysis showed that the vibration of the block skirts was more intense and the skirt was the main factor to influence the reliability of the engine. Cylinder head bolt force and piston slap force had significant effect on the top area of the block, and the surface vibration of the skirt was strongly influenced by the crank shaft load.
