Ejection Seat Cushion Comfort and Biomechanical Test Data

2026 research by Yixuan Guan presents experimental data from a 22-participant sitting comfort test and material compression test. The study evaluates three double-layer foam thickness ratios against a single-layer design, measuring subjective comfort ratings and objective pressure metrics.

Use Cases

• Analyze the correlation between subjective comfort ratings and objective metrics like maximum pressure (Pm) and average pressure (Pv).
• Model the relationship between foam thickness ratio (e.g., 1:2) and biomechanical outcomes such as contact area (Ac) and SAG factor.
• Compare pressure distribution performance (SPD%) across different cushion structures (single-layer N3 vs. double-layer N1/N3).
• Use interface pressure metrics and deformation data from compression tests to optimize foam layer design for support.

Strengths

• Includes data from 22 participants in controlled sitting comfort experiments.
• Compares three specific foam thickness ratios (1:1, 1:2, 2:1) with a baseline single-layer design.
• Measures multiple objective biomechanical indicators: Pm, Pv, Ac, SPD%, and SAG factor.

Limitations

• Small experimental scale with only 22 participants, limiting statistical generalizability.
• Data is embedded in a DOCX document (18.7 KB), requiring extraction and structuring for analysis.
• Temporal and geographic coverage of the participant sample and experiments is not specified.
