Summary

Hossein Towsyfyan's PhD thesis investigates the nonlinear tribological behavior of mechanical seals for online condition monitoring, focusing on acoustic emission measurements to detect faults at an early stage, specifically dry running, spring fault, and defective seal failures. The research uses a purpose-built test rig and signal processing methods to extract features that explain the tribological behavior of mechanical seals under healthy and faulty conditions. Mathematical models are developed to establish a relationship between acoustic emission root mean square value and working parameters of seals, showing a good agreement between measured and predicted signals, particularly in cases of leakage indicating seal failure. The study concludes that the acoustic emission measurement system and signal processing have potential for online diagnosis and monitoring of mechanical seals.
