When Angular Misalignment and Lubricant Viscosity Produce Similar Gear-Vibration Signatures: Conditional Distinguishability and Phase-Based Recovery — Research Data and Reference Package

This record provides research data and reference materials accompanying the manuscript “When Angular Misalignment and Lubricant Viscosity Produce Similar Gear-Vibration Signatures: Conditional Distinguishability and Phase-Based Recovery.” The package contains manuscript-reported evidence tables, declared source-state grids, numerical configurations, acceptance criteria, full-resolution figures, reviewer-audit scripts, and an independent reduced-model demonstration. It is intended to support evidence inspection, methodological reference, reviewer evaluation, and independent exploration of the proposed state-to-observation framework. The supplied materials are organized into three clearly separated categories: Reported evidence: numerical values, metrics, boundary fractions, and acceptance results reported in the associated study; Search grids and configurations: declared misalignment, viscosity, local-neighborhood, and conditional-boundary coordinates together with model and evaluation settings; Reference demonstration: an independently implemented reduced prescribed-gap Reynolds and normal–tilting observation model provided for methodological exploration. Demonstration outputs are explicitly separated from manuscript-reported evidence and are not presented as substitutes for the reported calculations. The package is intended as a research-data and reference resource; use of the included scripts is optional. A planned external-validation folder contains the benchmark protocol and requested-data schema for a possible comparison with Gao et al. (2026). It does not contain or redistribute data belonging to the Gao research group. Zenodo DOI: 10.5281/zenodo.21620809Version: 1.2.0Language: English
