Performance Assessment of a Class of Industrial Fans With Substantial Process Variability for On-Condition Monitoring and Contol System Design

Abstract

This paper presents a statistical quality control study for on-condition monitoring of draught fans in a steelmaking process. The study proposes a procedure for obtaining consistent estimates of peak vibration levels for performance assessment the machines based on independent measurements of the variable assuming the time between successive occurrences of the peak vibration were distributed with a probability density function.

Keywords: statistical quality control, probability density function, experimental design and modelling, vibration monitoring, on-condition performance assessment.
