Methods and apparatus for determining resilience of spring washers

A method enables the resilience (12) of a plurality of spring washers (74) stacked in a series arrangement (104) to be determined. The method comprises determining the potential energy for the series arrangement by integrating the product of the axial load (P) applied to the series arrangement, the...

Zusammenfassung:	A method enables the resilience (12) of a plurality of spring washers (74) stacked in a series arrangement (104) to be determined. The method comprises determining the potential energy for the series arrangement by integrating the product of the axial load (P) applied to the series arrangement, the displacement (Xs) of the series arrangement, and the number (Ns) of spring washers stacked in the series arrangement, and solving at least two non-linear equations to determine the resilience of the spring washers stacked in the series arrangement.
