Abstract


The crankshaft of the diesel engine is one of the most important parts of the entire engine . Damage and destruction it may cause damage to other parts of the diesel engine , especially with the reinforcement and technological development of the engine working conditions , so that the crankshaft is increasingly demanding . Crankshaft strength analysis and research has been ongoing work . In this paper, a lot of reading the basis of relevant literature last year , mainly from the following aspects 8L250 diesel engine crankshaft discussed : 1 ) the crankshaft stress analysis calculated the crankshaft in every 5 . Crank angle dynamic results . Click the crankshaft by classification societies Steel Ships specification strength check . 2) Pro-E crankshaft three - dimensional whole cane on the part model , and the interface between Pro-E and ANSYS - Workbench software , the part model is imported into ANSYS - Workbench software to generate the finite element model . 3) Application of ANSYS - Workbench software static analysis of the crankshaft . Discussed from the angle of the crankshaft boundary support conditions , the stress state in the rigid support conditions and non- rigid support conditions , and to make a comparative analysis . Derive the maximum value of the force of the crankshaft , according to the classification rules crankshaft fatigue strength check . 4 ) the application of ANSYS - Workbench software crankshaft finite element contact analysis . Drawn by the force of the crankshaft the entity bearing support conditions and deformation . And compared with the previous analysis . 5 ) prior to the adoption of diesel engine crankshaft strength finite element analysis to find out the point of maximum stress , the maximum stress does not affect the basic structure of the premise of the crankshaft optimization improvements , reduce the stress concentration points , and improved the specific method for the quantitative analysis . In the crankshaft to achieve the best optimization results .
