| Abstract: | In order to analyze the vulnerable spot of a crankshaft case which has a complex structure and is a key part of a diesel engine, a simplified mechanics model was established. The stress distribution of a crankshaft case of F165 diesel engine was calculated and analyzed by means of the finite element method. A test of validity was followed to examine the rationality of the new model. At last, a modified scheme to overcome the vulnerable spot of the crankshaft case was put forward based on the results obtained from the model. As a result, the reliability and the service life of the crankshaft case were remarkably improved. |
