YY/T 1560-2017 (China): Defines methodologies for evaluating the fatigue strength of spinal implant assemblies under complex loading.
ASTM F1717-18 (International): Standard test methods for spinal implant constructs in vertebrectomy models.
ASTM F2706-19: Specifies static and fatigue testing requirements for occipito-cervical and occipito-cervico-thoracic spinal implants.
Product Advantages
High-Frequency Stability: Advanced electromagnetic actuator maintains 0.1–15 Hz frequency range with ±0.05% force accuracy.
Ultra-Precision Loading: 50 kN axial force capacity with 1 N resolution for submicron displacement control.
Dynamic Load Control: Programmable R=0.1–10 load ratios with real-time stiffness compensation.
Biorelevant Environment: Temperature-controlled (37±1°C) lubrication bath with 20±2 g/L protein concentration.
Extended Durability: Capable of 10+ million cycle testing with <0.2% drift in calibration.
Modular Design: Six-station configuration allows parallel testing of multiple specimens.
Product Features
Electromagnetic Servo Motor: 50 kN axial force capacity with programmable load ratios (R=0.1–10).
Triaxial Strain Gauge: Measures axial/radial strains simultaneously (0.1 με resolution).
Dynamic Load Control: 0.1–15 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: Optional integration with micro-CT systems for in-situ crack analysis.
Safety System: Emergency stop, overload clutches, and laser-based specimen breakage detection.
