Finite Element Model Parameters for Wheelset-Track System Dynamics

A finite element model dataset for a wheelset-track system, used to study dynamic responses via explicit transient dynamic analysis. The dataset, created by Xiaonan Zhao and shared on figshare, was last updated on 2026-05-11. It contains parameters related to mass eccentricity, wheel-rail contact forces, and vibration energy across frequencies.

Use Cases

• Modeling the effect of mass eccentricity on wheel-rail contact forces based on the described dynamic response analysis.
• Analyzing vibration energy distribution in middle-high frequency ranges based on the described system response at different speeds.
• Investigating the relationship between dynamic unbalance and overall system vibration energy based on the parameter 'U' mentioned in the description.
• Studying the conditions leading to high-order wheel polygonal wear based on the described correlation between eccentric phase difference and unstable vibration frequency.

Strengths

• The dataset is associated with a specific research paper and methodology (explicit transient dynamic analysis).
• It is openly licensed under CC-BY-4.0 for reuse.
• File size is 9.5 KB, indicating a compact and likely focused parameter set.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description is technical but lacks specifics on the exact parameters contained in the XLS file.
