Condition-Based Maintenance
Research Guide
What is Condition-Based Maintenance?
Condition-Based Maintenance (CBM) is a strategy that uses real-time sensor data from engines to monitor health, detect faults, and predict remaining useful life for timely servicing.
CBM applies vibration analysis, performance monitoring, and prognostics algorithms to gas turbines, marine diesel engines, and aero engines. Key reviews include Tahan et al. (2017) with 422 citations on gas turbine health monitoring and Li and Nilkitsaranont (2009) with 222 citations on performance prognostics. Over 20 papers from the list address diagnostics in rotating machinery and emission-related monitoring.
Why It Matters
CBM reduces downtime and maintenance costs in aviation, marine transport, and power generation by enabling predictive servicing over scheduled overhauls (Tahan et al., 2017; Li and Nilkitsaranont, 2009). In marine diesel engines, it ensures reliable operation and emission compliance during voyages (Сагін et al., 2022). Gas turbine applications minimize rejection rates of blades and vanes, cutting repair expenses (Aust and Pons, 2019).
Key Research Challenges
Accurate Fault Prognostics
Developing reliable models for remaining useful life estimation from noisy sensor data remains difficult in varying operating conditions. Tsoutsanis and Meskin (2017) propose derivative-driven regression but note sensitivity to data quality. Tahan et al. (2017) highlight gaps in integrating diagnostics with prognostics for gas turbines.
Vibration Signal Processing
Extracting malfunction signatures from vibration data correlated with process variables challenges real-time implementation. Muszyńska (1995) outlines diagnostics methods but emphasizes need for advanced filtering. Applications in rotating machinery require handling non-stationary signals (Sallee, 1978).
Historical Data Utilization
Leveraging sparse historical performance data for deterioration modeling limits prognostic accuracy in fleet operations. Sallee (1978) analyzed JT9D data showing prerepair/postrepair trends, yet scaling to modern engines needs AI enhancements. Fast et al. (2008) demonstrate ANN feasibility but stress simulation data integration.
