Domain-Shift Aware Neural Networks for Unbalance Characterization in Rotating Systems

arXiv:2606.18882v1 Announce Type: cross Abstract: This work investigates the application of a domain-shift aware neural network for regression tasks aimed at estimating unbalance masses in rotating shafts under varying operating conditions. Experimental data were collected from a test rig in which a primary shaft, equipped with a flange carrying unbalanced masses, was driven at different rotational speeds, while a secondary shaft could be optionally activated to introduce domain discrepancy. The unbalance masses were positioned at a fixed radial distance, and the dynamic response of the system

Why this matters
Why now

The continuous advancements in AI and machine learning are enabling more sophisticated applications for predictive maintenance and industrial monitoring, making this a natural progression.

Why it’s important

This development allows for improved predictive maintenance in complex industrial machinery, potentially leading to increased operational efficiency, reduced downtime, and enhanced safety across sectors dependent on rotating systems.

What changes

The ability to accurately characterize unbalance in rotating systems despite changing operating conditions through AI reduces reliance on traditional, less adaptive methods.

Winners
  • · Industrial manufacturers
  • · Predictive maintenance software providers
  • · AI/ML industrial integrators
Losers
  • · Traditional diagnostic equipment manufacturers
  • · Maintenance service providers relying solely on reactive repairs
Second-order effects
Direct
