Abstract

PURPOSE: To carry out life control automatically and surely, by controlling vane life considering resonance, in the all ranges of running which includes starting and stopping.
CONSTITUTION: Approximate formula M.A. Miner is used for breaking condition due to fatigue of moving vane of turbine under running. Taking n for repeating numbers of vibration stress i, Ni for breaking repeating numbers, Kj for repeating numbers per cycle of sound at the j th resonance point, 1 for the number resonance point in a range of running in the approximate formula 6, if the vibration of vane is detected, ni, Kj are found. That is, the flowchart shows turbine moving vane 11, vibration detecting 12, number of breaking repetition 13, calculation 14 of formula 6, judgement 15 of value ≤ of formula 6, continuation of running 16, running stop 17, moving vane test 18, value > 1 of formula 6 for 19, value = 0 of formula 6 for 20, thereby vane life can be controlled automatically.
