Calculation in accordance with DIN 743
Calculation in accordance with DIN 743 (200)) "Bearing capacity of shafts and axles": Strength calculation for shafts and axles with safety verification against lasting deformation and fatigue fracture.
The occurring stresses (with middle stress and deflection stress) are evaluated based on the simplified Smith diagram.
Important characteristics of this method:
Calculation in accordance with the FKM guideline
The current version of the FKM guideline (Strength Verification, 4th edition) is the most comprehensive calculation method available today. It goes far beyond the application area of DIN 743, however it is more demanding in the interpretation of the results.
The calculation algorithm contains the latest findings in material theory and executes a static calculation as well as a time yield calculation. The calculation algorithm has been developed by professor Haibach. Thus assurance for expert interpretation of this complex guideline is provided.
Strength calculation with load spectra
Calculation in accordance with the FKM guideline permits strength calculation with load spectra. If a shaft has been entered with load spectra, then the calculation can be directly executed. With the calculation methods in accordance with Hänchen/Decker load spectra cannot be taken into account because the standard does not allow it.
With DIN 743 the strength calculation can also be executed with load spectra. The calculation is executed in the same manner as as specified in an FVA draft. A supplement of DIN 743 is planned.
For all methods, alternatively it is possible to execute a fatigue strength verification for a specific load spectrum element.
