Less Pain to Predict Strain

Vibrations from large power generators can steadily weaken their own supporting structures over time. By themselves, pure analytical models of the strain history on the metal frame are not nearly accurate enough without good experimental correlation.

Cummins developed a new spin on a decades-old challenge of generator set durability modeling by integrating True-Load’s strain correlation models with its overall structural analysis in Ansys Mechanical to rev up its simulation workflow.
