Calculating the estimated fatigue life of a disc spring

摘要

Disc springs are extremely useful components in a wide range of applications, being able to be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling. And they can be used singly or in multiples, stacked parallel, in series or in a combination thereof. But perhaps what makes them unique is that, based on standardised calculations, the deflection for a given load is predictable and the minimum life cycle can be determined. Here we look at how.
