Femoral Stem Neck Prostheses Fatigue Testing Machine

Standard 

• YY/T 0809.6 (China): Specifies neck fatigue testing for femoral stems in partial/total hip arthroplasty.
• ISO 7206-6 (International): Defines protocols for evaluating the fatigue strength of femoral head-neck junctions.
• ASTM F2023: Additional compliance for dynamic loading of ceramic femoral heads.
• Adaptive Protocols: Customizable for emerging standards in biomaterial fatigue testing.

Product Advantages

1. Electromagnetic Precision: M-Series actuator delivers ±0.1% force accuracy with sub-micron displacement control.
2. 10 Million Cycle Endurance: Proven capability to complete ISO 7206-6’s 10⁷-cycle fatigue test without drift.
3. R=0.1 Load Control: Advanced servo-hydraulic system maintains specified stress ratios throughout testing.
4. Real-Time Failure Detection: AI-driven algorithm identifies crack initiation at sub-millisecond intervals.
5. Ergonomic Workflow: 15.6” touchscreen with multilingual interface (English/Chinese/German) and pre-loaded SOPs.
6. Modular Test Chambers: Quick-swap environmental pods for simulated physiological testing (-20°C to +50°C).
