Vibration Signal Analysis of Complex Mechanical Systems and Early Wear Detection and Forecasting for Gears
Bibliographic record
Abstract
With the advancement of modern industrial technology, complex mechanical systems have found extensive applications across various industries.Gears, integral components of these systems, play a crucial role in determining the stability and safety of the entire system.Wear and aging of system components during prolonged operations might lead to performance degradation or system failures.Historically, numerous methods for vibration signal analysis and gear wear detection have been proposed.However, these methods often exhibit limitations when applied to intricate systems, such as reliance on empirical rules and suboptimal handling of nonlinear vibration signals.In light of these challenges, the vibration genesis mechanism in complex mechanical systems has been deeply investigated.A "Gear Health Factor" has been introduced, and a wear prediction model for gears, incorporating Bidirectional Long Short-Term Memory (Bi-LSTM) networks and attention mechanisms, has been developed.This research offers fresh perspectives and methods for the health management of complex mechanical systems and holds significant practical implications.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
