Shaft Fatigue
With the Nauticus Machinery Shaft Fatigue software you can dimension and evaluate marine shafting systems in addition to calculating load-carrying capacity.
Marine shaft software
- Calculates allowable torsional vibration stress levels based on low cycle, high cycle and transient fatigue
- Applicable for marine propulsion and auxiliary shafts onboard ships and marine applications
- Calculates load-carrying capacity based on methods described in DNV’s Classification Note no. 41.4
- Calculation method mainly based on DIN 743 Part 1-3: 2000-04 and VDEH 1983 – adapted to marine applications
- Calculates ice class strength according to Finnish-Swedish Ice Class Rules and IACS Polar Ice Class Rules
- Includes empirical formulas for calculation of stress concentration factors for all common “stress raisers” in marine shafts
- For direct coupled propulsion systems, geared propulsion systems and generator sets
Key benefits of the Shaft Fatigue software module
- Helps you avoid unnecessary shaft failure with advanced shaft fatigue software analysis
- Efficient determination of load-carrying capacity for shafts
- Calculates several critical sections of the shaft in one batch
- Easy input of notch geometry by extensive use of relevant figures
- Easy to do parameter studies for stress concentration factors
- Uses simplified methods (less input) or detailed methods (more input)
- Estimation of maximum torque load and blade failure load due to ice impacts
- Accumulated shaft fatigue analysis due to ice impacts
- Guidelines and default parameters supporting ice class calculations
- The full report contains both main class and ice class results
