Intervertebral Fusion Cages Shear Fatigue Tester

Standard 

• YY/T 0959-2014 (China): Specifies shear fatigue testing protocols for intervertebral fusion devices, including load ratios, frequency, and failure criteria.
• ASTM F2077-17 (International): Defines methodologies for evaluating the fatigue strength of intervertebral body fusion devices under shear loading.
• ISO 12189-1: Additional compliance for mechanical testing of spinal implant components.

Product Advantages

1. Multi-Angle Shear Control: Dual-axis actuator system provides 0°–45° adjustable shear plane orientation.
2. Dynamic Load Precision: Electromagnetic servo motor maintains R=0.1 load ratio with ±0.05% accuracy.
3. 5 Million Cycle Endurance: Proven capability to complete YY/T 0959’s 5×10⁶-cycle fatigue test without calibration drift.
4. Real-Time Deformation Monitoring: 3D digital image correlation (DIC) tracks micro-strains during testing.
5. Biorelevant Environment: Temperature-controlled (37±1°C) lubrication bath with 20±2 g/L protein concentration.
6. Modular Test Chambers: Quick-swap pods for simulated physiological (-20°C to +50°C) and corrosive environments.
