Choice of the best time scale for system reliability analysis

摘要: Abstract Several time scales (total operation time, the number of high and load cycles, low their linear combinations, etc.) are compared. Examples test field data analyzed it is shown that possible to find a combination different which guarantees considerable decrease in coefficient variation (c.v.) system lifetime. It means that, using this ‘optimal’ scale, an accurate reliability prediction can be done for wide spectrum loading conditions. A formal model selecting optimal (‘load invariant’) scale described. In e-quantiles lifetime under various loadings maximally ‘compressed’ terms c.v. ‘Artificial’ based on damage counters suggested some aspects use discussed.
