Crankshaft design software for calculations of fatigue

Crankshaft Fatigue

The Crankshaft Fatigue software module calculates the safety against fatigue based on DNV GL’s Classification Note no. 41.3 (2002). It also covers the corresponding calculation method according to the CIMAC/IACS method.

Crankshaft design software for calculating fatigue

  • Calculation and analysis of safety against crankshaft fatigue failure in diesel engines, and safety against slippage for semi built crankshafts
  • Fatigue check based on DNV GL’s Classification Note no. 41.3 (2002)
  • Corresponding calculation method according to the CIMAC/IACS method
  • Applies to diesel engines for both main propulsion and auxiliary purpose
  • Applies to solid forged per semi built crankshafts of forged and cast steel with one crank throw between main bearings

Key benefits of the Crankshaft Fatigue software module

  • Calculation according to DNV GL Rules and CIMAC/IACS (IACS bluebook M53) in the same tool
  • Import functions for cylinder pressures or theoretical calculation method
  • Flexible input options (use pre-defined input for e.g. stress concentration factors or let the program calculate it)
  • Advanced report generator
