Intramedullary Nails Four - point Bending Fatigue Tester

Standard

• YY/T 0591-2011: Chinese standard specifying bending fatigue test methods for intramedullary nails and locking screws, including load application, cycle counting, and failure criteria.
• ASTM F1264: International standard covering fatigue testing of intramedullary fixation devices, with protocols for sinusoidal loading at 5Hz–20Hz frequencies.

Product Advantages

1. Precision Fatigue Testing:
   • Electromagnetic servo-controlled loading system ensures sinusoidal force application with ±0.5% accuracy, adhering to ASTM F1264’s frequency and load requirements.
   • Adjustable R-ratio (0.1–0.9) and load range (100 N–10,000 N) for versatile testing scenarios.
2. Customized Fixturing:
   • Modular four-point bending clamps with interchangeable roller diameters (8–16mm) and contour-matching designs to accommodate diverse nail diameters and lengths.
   • Anti-slip mechanisms and specimen alignment guides for consistent results.
3. Advanced Data Acquisition:
   • Real-time monitoring of cycles, load, and displacement with 5000Hz sampling rate.
   • Automatic calculation of key parameters: fatigue life (N cycles to failure), fatigue strength (S-N curve generation), and crack initiation points.
4. User-Centric Design:
   • Intuitive software with preloaded SOPs for YY/T 0591 and ASTM F1264 compliance.
   • Multi-language interface (English/Chinese/Spanish) and exportable reports (PDF/Excel/CSV).
5. Durability & Safety:
   • Corrosion-resistant steel frame and overload protection system for long-term reliability.
   • Low-noise operation (<65 dB) suitable for laboratory environments.
