How to Estimate the Fatigue Life of Helical Compression Springs

Fatigue is the failure of a component as a result of cyclic stress. Fatigue happens in multiple stages and can have significant impact on your application.

This white paper provides effective methods for estimating the fatigue life of helical compression springs during the design phase. The white paper includes:

  • Definition and discussion on fatigue and fatigue characteristics
  • Review of how fatigue test data has been evaluated in the past
  • Spring-specific Modified Goodman diagrams and instructions for use
  • A comparison between the direct calculation of predicted life with Modified Goodman diagrams and traditional graphical methods.
