| Abstract: | In order to improve the safety factor of crankshaft fillet fatigue of large cylinder diameter marine diesel engine,the crankshaft system model is built and AVL-PU software is used for fatigue calculation.It shows that the fatigue safety coefficient is only 0.974,which can not meet the required value 1.05.Based on the existing calculation results,the optimized structure of the crankshaft fillet is proposed,different compound fillet projects are designed,and the simulation and comparison calculation are carried out.The results show that the minimum fatigue safety factor of the optimized compound fillet is 1.064,which meets the required value. |
