| Abstract: | The torsional vibration, stress concentration and endurance fatigue strength of a V12 engine crankshaft were analyzed. According to the IACS UR M53 standard and CCS Rules for Classification of Sea-going Steel Ships, the nominal stress at the crankshaft main journal fillets, crankpin fillets and crankpin oil bore outlets were measured, and the equivalent stress and minimum safety factor were calculated by 1D analysis method. The calculation results show that the crankshaft design can meet with IACS UR M53 standard and CCS Rules for Classification of Sea-going Steel Ships. |
