Tibial Tray Fatigue Testing Machine

Standard 

• YY/T 0810 (China): Specifies fatigue testing protocols for tibial trays in total knee arthroplasty, focusing on support and protection of plastic bearing surfaces.
• ASTM F1800 (International): Defines methodologies for evaluating the fatigue strength of tibial components under cantilever loading conditions.
• ISO 14879-1: Additional compliance for general fatigue testing of total knee joint prostheses.

Product Advantages

1. Cantilever Loading Precision: Advanced actuator design ensures uniform stress distribution per ASTM F1800 requirements.
2. 5 Million Cycle Endurance: Proven capability to complete YY/T 0810’s 5×10⁶-cycle fatigue test without calibration drift.
3. Dynamic Load Control: Closed-loop system maintains R=0.1 stress ratio during sinusoidal/random loading (0.1–10 Hz).
4. Real-Time Fracture Detection: AI-powered acoustic emission monitoring identifies micro-cracks at sub-millisecond intervals.
5. Intuitive Workflow: 21.5” capacitive touchscreen with gesture control and pre-loaded SOPs for 10+ implant geometries.
6. Modular Environmental Chambers: Quick-swap pods for simulated physiological (-20°C to +50°C) and corrosive environment testing.

Product Features

• Electromagnetic Actuator: 3,000 N peak force capacity with programmable load ratios (R=0.1–10).
• Cantilever Loading System: Simulates physiological knee joint moments with ±20 mm axial displacement.
• 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-Speed Imaging Ready: Syncs with external cameras for full-field strain mapping (DIC optional upgrade).
• Safety First: Triple-redundant emergency stop, overload clutches, and laser-based specimen breakage detection.
