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.
