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

Multi-Angle Shear Control: Dual-axis actuator system provides 0°–45° adjustable shear plane orientation.

Dynamic Load Precision: Electromagnetic servo motor maintains R=0.1 load ratio with ±0.05% accuracy.

5 Million Cycle Endurance: Proven capability to complete YY/T 0959’s 5×10⁶-cycle fatigue test without calibration drift.

Real-Time Deformation Monitoring: 3D digital image correlation (DIC) tracks micro-strains during testing.

Biorelevant Environment: Temperature-controlled (37±1°C) lubrication bath with 20±2 g/L protein concentration.

Modular Test Chambers: Quick-swap pods for simulated physiological (-20°C to +50°C) and corrosive environments.

Product Features

Electromagnetic Servo Motor: 10 kN axial/shear force capacity with programmable load ratios (R=0.1–10).

Adjustable Shear Plane: Motorized 0°–45° tilt mechanism with laser alignment system.

Dynamic Load Control: 0.1–10 Hz frequency range with programmable waveforms (sine, square, random, custom).

Thermal-Mechanical Chamber: ±0.3°C temperature stability with integrated humidity control (10–95% RH).

High-Resolution Imaging: Built-in 5MP camera system for crack propagation analysis.

Safety System: Emergency stop, overload clutches, and laser-based specimen breakage detection.
