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
Electromagnetic Precision: M-Series actuator delivers ±0.1% force accuracy with sub-micron displacement control.
10 Million Cycle Endurance: Proven capability to complete ISO 7206-6’s 10⁷-cycle fatigue test without drift.
R=0.1 Load Control: Advanced servo-hydraulic system maintains specified stress ratios throughout testing.
Real-Time Failure Detection: AI-driven algorithm identifies crack initiation at sub-millisecond intervals.
Ergonomic Workflow: 15.6” touchscreen with multilingual interface (English/Chinese/German) and pre-loaded SOPs.
Modular Test Chambers: Quick-swap environmental pods for simulated physiological testing (-20°C to +50°C).
Product Features
Electromagnetic Actuator: 5.340 N peak force capacity with 0.001 N resolution.
Dual-Axis Loading: Simultaneous axial/torsional loading (50 Nm max torque).
Dynamic Load Control: 1–30 Hz frequency range with programmable waveforms (sine, square, random).
Thermal Chamber Integration: ±0.5°C temperature stability for accelerated aging studies.
High-Speed Imaging Ready: Syncs with external cameras for full-field strain mapping (optional upgrade).
Safety First: Emergency stop, overload clutches, and laser-based specimen breakage detection.
