A torsional study evaluates crankshaft, coupling, and gears to ensure torsional vibration is acceptable
MODEL DESCRIPTION
A cross-section of the model train developed by Engineered Solutions Group is shown above in first graphic. Geometry was defined by drawings and data sheets supplied by the client. The model was generated and analyzed using the DyRoBeS finite element rotor dynamics program and consisted of 3 shafts with 45 elements and 69 sub-elements. A description of the DyRoBeS Software is included at the end of the report. The model was developed using general procedures outlined in references [1] and [1].

Torsional Analysis
ESG vibration experts use our field-proven proprietary simulation software to:
- Conduct a modal analysis of the mass elastic model to determine Torsional Natural Frequencies (TNFs),
- Assess the torque effort curves for all key operating conditions,
- Perform a forced response analysis to accurately predict torsional vibration and stress, and
- Recommend solutions to ensure a safe torsional system.
