The Intervertebral Fusion Cages Shear Fatigue Tester is a specialized biomechanical testing device used to evaluate the shear fatigue performance of intervertebral fusion cages, which are implants designed to stabilize spinal segments. It simulates repetitive shear loads that the implant would experience in the human spine over time, helping to assess durability, structural integrity, and long-term safety before clinical use.
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.
Application
The Intervertebral Fusion Cages Shear Fatigue Tester is used to evaluate the mechanical durability and fatigue resistance of spinal fusion cages under repeated shear loading. It helps manufacturers and researchers assess implant performance, predict long-term reliability, and ensure compliance with biomechanical testing standards before clinical use.
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.
Product Features
(1)Electromagnetic Servo Motor: 10 kN axial/shear force capacity with programmable load ratios (R=0.1–10).
(2)Adjustable Shear Plane: Motorized 0°–45° tilt mechanism with laser alignment system.
(3)Dynamic Load Control: 0.1–10 Hz frequency range with programmable waveforms (sine, square, random, custom).
(4)Thermal-Mechanical Chamber: ±0.3°C temperature stability with integrated humidity control (10–95% RH).
(5)High-Resolution Imaging: Built-in 5MP camera system for crack propagation analysis.
Safety System: Emergency stop, overload clutches, and laser-based specimen breakage detection.
