Bone Plates Four-point Bending Fatigue Tester

• 

Standard

YY/T 1503-2016: Chinese standard specifying test methods for bending fatigue properties of metallic bone plates, requiring 1 million cycles or failure at 5Hz frequency and R=0.1.

ASTM F382: International standard for metallic bone plates, covering material specifications, mechanical testing (including fatigue), and quality assurance protocols.

Product Advantages

Precision Load Control:

Electromagnetic servo-controlled loading system ensures sinusoidal force application with ±0.5% accuracy, adhering to YY/T 1503’s 5Hz frequency requirement.

Adjustable R-ratio (0.1–0.9) and load range (10 Nm–1.000 Nm) for versatile testing scenarios.

Customized Fixturing:

Modular four-point bending clamps with interchangeable roller diameters (6–13mm) and contour-matching designs accommodate diverse bone plate geometries.

Anti-slip mechanisms prevent specimen displacement during high-cycle testing.

Advanced Testing Protocols:

Preloaded SOPs for fatigue life (N cycles to failure) and fatigue strength (S-N curve generation) per ASTM F382.

Optional axial-torsional coupling for simulating combined loading in complex fracture scenarios.

Data Integrity:

Real-time monitoring of cycles, torque, and angular displacement with 5000Hz sampling rate.

Automatic report generation (PDF/Excel) with statistical analysis of median fatigue strength at 10⁶ cycles.

Durability & Safety:

Corrosion-resistant steel frame and overload protection system ensure longevity and operator safety.

Low-noise operation (<65 dB) for lab-friendly use.

Product Features

Load Capacity: 10 Nm–1.000 Nm (torsional) / 5 kN (axial).

Frequency Range: 0.01–100 Hz (adjustable for static/dynamic tests).

Temperature Control: Optional environmental chamber (-20°C to +150°C) for simulating physiological conditions.

Software Suite:

Intuitive interface with multi-language support (English/Chinese/Spanish).

Customizable test profiles and compliance with 21 CFR Part 11 for audit trails.

Calibration: NIST-traceable certification included, with annual recalibration service available.
