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
- 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.
- 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.
- 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.
- 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).
- Durability & Safety:
- Corrosion-resistant steel frame and overload protection system for long-term reliability.
- Low-noise operation (<65 dB) suitable for laboratory environments.
Product Features
- Load Capacity: 100 N–10,000 N (axial) / 50–500 Nm (torsional).
- Frequency Range: 0.01–20 Hz (adjustable for static/dynamic tests).
- Temperature Control: Optional environmental chamber (-20°C to +150°C) for simulating physiological conditions.
- Software Suite:
- Customizable test profiles with automated pass/fail criteria.
- 21 CFR Part 11 compliance for audit trails and electronic signatures.
- Calibration: NIST-traceable certification included, with annual recalibration available.
