Helmet Surface Shear Force and Friction of Protrusions Tester
Standard
- ECE R22.06 (UN/ECE regulation for motorcycle helmet safety and protrusion resistance)
- GB 811-2022 (China’s national standard for helmet structural integrity and surface friction)
- ISO 10256-5 (Headgear testing – Protrusion shear resistance and abrasion performance)
Product Advantages
- Dual-Testing Precision
- 15kg impact mass: Replicates sudden shear forces from collisions.
- 400N loading mechanism: Tests surface friction under static and dynamic loads.
- Electromagnetic Precision
- Zero-friction release: Ensures repeatable 500mm free-fall tests (±1mm accuracy).
- Adjustable headform: Fits EN 960 S/M/L sizes with 360° rotation.
- Abrasion Simulation
- Interchangeable friction media: Sandpaper (P80–P400 grit) and shear blocks for real-world surface testing.
- Linear guide system: Maintains 10N constant force during abrasion cycles.
- Safety First Design
- Overload protection: Halts tests if forces exceed 500N (20% safety margin).
- Emergency stop: Instantly retracts loading mechanism during malfunctions.
- Data-Driven Compliance
- Automated reporting: Generates ECE R22.06/GB 811-2022-compliant certificates.
- Historical data review: Compares up to 10,000 tests via cloud-connected software.
Product Features
Shear Force Testing
- Impact System:
- 15kg stainless steel mass: 500mm free-fall height (±1mm accuracy).
- Electromagnetic release: Ensures consistent impact velocity (3.13 m/s).
- Headform Assembly:
- Biofidelic headform: EN 960-compliant with aluminum alloy skeleton.
- Adjustable neck brace: Simulates natural head movement during testing.
Friction Testing
- Abrasion Module:
- Horizontal guide frame: Holds sandpaper/shear blocks for linear motion.
- 400N loading cell: Applies constant force (±0.5N accuracy).
- Control System:
- HMI Interface: 10.1" touchscreen with live force/displacement curves.
- PID Force Control: Maintains 400N ±1% during friction cycles.
Safety Systems
- Interlocked enclosure: Prevents access during testing (Category 3 safety rating).
- Auto-eject mechanism: Retracts headform if misalignment detected.
