TORSIONAL VIBRATION STRESS AND FATIGUE STRENGTH ANALYSIS OF MARINE PROPULSION SHAFTING SYSTEM BASED ON ENGINE OPERATION PATTERNS

Torsional Vibration Stress and Fatigue Strength Analysis of Marine Propulsion Shafting System Based on Engine Operation Patterns

Modern merchant ships use marine propulsion systems equipped with an ultra-long-stroke diesel engine that directly drives a large slow-turning propeller.Such systems use fewer cylinders and generate greater power at slower shaft speeds, which affords improved propulsion performance as well as low repair and maintenance costs.However, this also resu
