Introduction
1. Core design specifications and technological breakthroughs
1.1 System space specifications
| Functional area | Minimum size | Material requirements |
|---|---|---|
| Wheelchair positioning area | 750×1300mm | Friction coefficient 0.65-0.80 |
| Grip height | 720-910mm | Diameter 25-40mm |
1.2 Dynamic performance threshold
Based on the verification indicators of Appendix B:
- Maximum acceleration load: 3g@rearward for 1.5 seconds
- Structural rigidity: deformation <50mm or fracture potential energy absorption＞9.6kJ
II. Key test methodology
2.1 Collision dynamics simulation
| Test type | Acceleration module | Indicator verification |
|---|---|---|
| Braking (1g) | Figure A.1 Pulse spectrum | Point P offset ≤150mm |
| Turning (0.75g) | Figure A.3 Curve | Point H relative displacement ratio ≥1.1:1 |
2.2 Biomechanical verification
- Lumbar spine flexibility: flexion stiffness 175-225N·m/rad (Figure D.1)
- Knee displacement priority: Xknee/Xwheel ratio dynamic monitoring
III. Evolution of standard application
Comparison of the implementation gap between European and American standards:
| Parameter comparison | Requirements of this document | FMVSS® standard |
|---|---|---|
| Brake test load | 1g×272kg | 0.8g×300kg |
| Lock fatigue test | 5000 times | 3000 times |
