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).

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.
