    Failure Rate, Bathtub Curve and Reliability of Components and Systems.

  • Original language description

    The paper defines the failure rate and explains its characteristic development in time (bathtub curve). It also explains the difference between the mean time between failures (MTBF) and useful life, and shows the use of failure rate for reliability evaluation and in design. The shape parameter of Weibull distribution for times to failure is related to the bathtub curve and can indicate the basic reasons for some kinds of failures. The second part of the paper is devoted to the methods for reliability increasing, especially in design stage: Failure mode and effect analysis, Fault tree analysis, robust design, computer simulation, testing of all components before assembling, proof testing and diagnostics

    Intenzita poruch, vanová křivka a spolehlivost konstrukcí

  • Czech description

    Ćlánek vysvětluje intenzitu poruch a její vývoj v čase (vanová křivka). Vysvětluje také rozdíl mezi střední dobou mezi poruchami a užitečným životem a ukazuje použití intenzity poruch při posuzování spolehlivosti a při návrhu. parametr tvaru Weibullova rozdělení souvisí s typem porušení. Druhá část příspěvku je věnována metodám zvyšování spolehlivosti: FMEA, FTA, robustní design. počítačová simulace, diagnostika a další.
