A 493.7 KB Excel dataset containing a simplified model of a hydro-generator shaft system with two rotors. The model, created by Tengjiao Guo, incorporates electromagnetic, mechanical, and flow excitation. It uses a 'shape guidance' strategy based on test signal libraries to analyze axis trajectories and correlate them with frequency components and excitation sources.
Use Cases
- Simulating rotor dynamics and vibration responses based on the described electromagnetic, mechanical, and flow excitations.
- Analyzing axis trajectory shapes to identify dominant frequency components as mentioned in the description.
- Correlating measured trajectory patterns with specific physical driving components for fault diagnosis.
- Validating simplified engineering models for hydro-generator shaft systems against test signal data.
Strengths
- Model incorporates multiple excitation sources (electromagnetic, mechanical, flow) as described.
- Dataset is openly shared under a CC-BY-4.0 license, facilitating reuse.
- File is provided in the widely compatible XLSX format.
Limitations
- Row count and column definitions are unknown, limiting suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- The dataset is small (493.7 KB), indicating a limited scope or a highly simplified model.
