At the same time the range of the constant failure rate ends.
2.
It assumes a constant failure rate over time.
3.
It represents the time of constant failure rate in the failure rate bathtub curve.
4.
Since constant failure rates are only valid during the useful life period, this metric is valuable for interpreting FMEDA result limitations.
5.
Solid niobium capacitors with manganese dioxide electrolyte have no wear-out mechanism so the constant failure rate lasts up to the point all capacitors have failed.
6.
The middle portion of the bathtub, or'useful life', is a slightly inclined, nearly constant failure rate period where the consumer enjoys the benefit conferred by the product.
7.
Physics of failure is typically designed to predict wearout, or an increasing failure rate, but this initial success by Black focused on predicting behavior during operational life, or a constant failure rate.
8.
Sherlock performs several different types of reliability analysis and provides the useful ( constant failure rate ) and wear out ( increasing failure rate ) portions of the life curve for each mechanism-component combination.
9.
Erroneous expression of the failure rate in % could result in incorrect perception of the measure, especially if it would be measured from repairable systems and multiple systems with non-constant failure rates or different operation times.
10.
This calculation requires that the system is working within its " useful life period ", which is characterized by a relatively constant failure rate ( the middle part of the " bathtub curve " ) when only random failures are occurring.
