How to Calculate the Estimated Fatigue Life of a Disc Spring
Disc Springs are conically-shaped washers designed to be axially loaded. They can be used individually or assembled into stacks to achieve the desired force-deflection characteristic required for the application. Since deflection of a Disc Spring at a given load is predictable, it is possible to calculate force and stress levels within the Disc. This paper focuses on the use of Disc Springs and how to estimate fatigue life in dynamic situations.
