The Intramedullary Nails Four-Point Bending Fatigue Tester is a specialized testing device designed to evaluate the fatigue performance and mechanical durability of intramedullary nails under cyclic bending loads. It applies repeated four-point bending forces to simulate long-term in vivo stresses, allowing assessment of nail strength, flexibility, and resistance to fracture over time. This tester is widely used in orthopedic research, product development, and quality control to ensure intramedullary nails meet required mechanical reliability standards.
Standard
(1)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.
(2)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.
Product Features
(1)Load Capacity: 100 N–10.000 N (axial) / 50–500 Nm (torsional).
(2)Frequency Range: 0.01–20 Hz (adjustable for static/dynamic tests).
(3)Temperature Control: Optional environmental chamber (-20°C to +150°C) for simulating physiological conditions.
(4)Software Suite:
Customizable test profiles with automated pass/fail criteria.
21 CFR Part 11 compliance for audit trails and electronic signatures.
(5)Calibration: NIST-traceable certification included, with annual recalibration available.
