| Abstract: | Taking the crankshaft of a high speed diesel engine as an object of study, its stress status on the biggest stresses and torsion load is analyzed by FEA. According to the obtained average stresses and the stresses spectrum, its fatigue strength is judged. By analyzing its structural parameters and the dimensions, their relations to the design are discussed. The final result shows that the crankshaft is of higher reliability with safety factor of 3.2. |
