Abstract

Det blir foreslått en fremgangsmåte for vurderingen av restlevetiden til en innretning som under driften er utsatt for slitasje, med følgende trinn: a) for minst en karakteristisk parameter (t) som er sensitiv for slitasjen (V) blir det beregnet en sammenheng med en tidsstørrelse (A) som er representativ for driftsvarigheten, b) for den karakteristiske parameteren (T) blir det fastsatt en grenseverdi (G) som angir den maksimale slitasjen som kan tillates, c) det blir oppstilt et kjenningsfelt (KF) som angir en sammenheng mellom den karakteristiske parameteren (T), tidsstørrelsen (A) og slitasjen (V), d) ved hjelp av data registrert måleteknisk blir den virkelige verdien for den karakteristiske parameteren (T) avhengig av tidsstørrelsen beregnet, e) av den virkelige verdien blir det hver gang ved hjelp av kjenningsfeltet (KF) beregnet den foreliggende slitasjen (V) i øyeblikket, f) i det man går ut fra den virkelige verdien i øyeblikket for den karakteristiske parameteren (T) blir ved hjelp av ekstrapolering på grenseverdien (G) bestemt for hvilken sluttverdi for tidsstørrelsen (A) den maksimale tillatte slitasjen blir nådd, g) gjennom sammenligning av denne sluttverdien med verdien for tidsstørrelsen som hører med til den foreliggende slitasjen i øyeblikket blir restlevetiden (RL) vurdert.
