BelleFlex™ Home / Tech Tips / Determining Fatigue Life

How do you determine fatigue life?

Fatigue life refers to the number of cycles a spring can withstand before it fails in a particular application. The fatigue life is based on the dimensions of the spring or spring stack, the pre-load, the final load, the deflection, and the frequency. The goal of determining the fatigue life is to ensure that your Belleville solution will be able to withstand the stress to which it will be exposed. In situations in which a single Belleville cannot withstand the level of stress, a well-designed stack of Bellevilles can increase the fatigue life.

BelleFlex™ engineers provide assistance in determining fatigue life for your specific application.
