Condition monitoring of combined fault scenarios in rotating machinery by integrating vibration based analysis and design of experiments

摘要

This paper aims to quantify the effects of combined faults in rotating machinery using vibration based condition monitoring using DOE (Design of Experiments) approach. The quantified contribution of faults and their interactions to overall severity in multiple defect scenarios creates better understanding of the dynamics of faults. Practically, it helps to improve design as well as guide the maintenance decisions by the user of any rotating machinery. This paper presents a sample investigation and demonstration into the quantification of the effects for the combination of two most common but critical defects of rotating machinery: Static Unbalance and Parallel Misalignment. Besides, the quantification, the DOE approach is also utilized to analyze the effects of combined faults in combined fault scenarios in rotating machinery
