Bearing Misalignment Effects on Rotordynamics with Full Stiffness Matrix

Giota Goswami's research dataset investigates the rotordynamic effects of misalignment and arrangement in angular contact ball bearings. It employs a full stiffness matrix with cross-coupling terms and a 3D solid finite element rotor model. The dataset was last updated in April 2026.

Use Cases

• Analyze changes in bearing stiffness due to misalignment using the full stiffness matrix.
• Model the effect of contact force distribution on rotor critical speeds.
• Study the impact of bearing arrangement on rotor mode shapes.
• Validate finite element rotor models against experimental bearing misalignment data.

Strengths

• Includes a full ball bearing stiffness matrix with cross-coupling terms.
• Based on a three-dimensional solid finite element rotor model.

Limitations

• Dataset scale is small at 6.3 MB, suggesting limited raw numerical data.
• Specific row counts and column structures are unknown.
• Focus is on a specific bearing type and misalignment scenario, limiting generalizability.
