THE LOGIC OF RELIABILITY LIMITS TO ENSURE HIGH QUALITY DATA

摘要

A reliability range is determined for a parameter of a component in a machine subjected to life reducing loads during operation, comprising the steps of: acquiring, for each of a plurality of load sessions, at least one parameter value for said component; generating a distribution pattern containing said parameter values for the plurality of load sessions; assigning a reliability range for the distribution pattern, wherein parameter values outside said reliability range are considered as being unrealistic; analyzing the parameter values outside the reliability range to determine which of said parameter values outside the reliability range are confirmed to be unrealistic; and adjusting the reliability range if a ratio between the confirmed unrealistic parameter values and the considered unrealistic parameter values is outside a further range being predetermined for the ratio.
