Torsional Fatigue Tester - China

Standard

YY/T 0857-2011 (China): Specifies torsional fatigue testing protocols for spinal pedicle screw-rod systems, including load ratios, frequency, and failure criteria.

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

Multi-Axis Torsion Control: Advanced electromagnetic actuators maintain R=-1 load ratio (fully reversed torsion) with ±0.05% accuracy.

5 Million Cycle Endurance: Proven capability to complete YY/T 0857’s 5×10⁶-cycle fatigue test without calibration drift.

Dynamic Angle Control: 0.001° resolution ensures precise replication of physiological spinal motion.

Real-Time Fracture Detection: AI-powered acoustic emission monitoring identifies micro-cracks at sub-millisecond intervals.

Intuitive Workflow: 21.5” capacitive touchscreen with gesture control and pre-loaded SOPs for 10+ implant geometries.

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

Product Features

Electromagnetic Servo Motors: Dual-axis torsional actuators (±180° rotation, 50 Nm peak torque).

6-DOF Kinematic Simulation: Replicates natural spinal motion (flexion/extension ±20°, lateral bending ±15°, axial rotation ±10°).

Dynamic Load Control: 0.1–5 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-Speed Imaging Ready: Syncs with external cameras for full-field strain mapping (DIC optional upgrade).

Safety System: Triple-redundant emergency stop, overload clutches, and laser-based specimen breakage detection.
