Femoral Stem Fatigue Performance Testing Machine

Standard

• YY/T 0809.4 (China): Specifies fatigue testing protocols for femoral stems in partial/total hip arthroplasty.
• ISO 7206-4 (International): Defines methodologies for evaluating the fatigue strength of femoral stem-bone cement interfaces.
• ASTM F2580: Additional compliance for impact resistance testing of modular femoral necks.
• Adaptive Protocols: Customizable for emerging standards in additive-manufactured implant evaluation.

Product Advantages

1. Electromagnetic Precision: M-Series actuator delivers ±0.05% force accuracy with 0.001N resolution.
2. 5 Million Cycle Endurance: Proven capability to complete ISO 7206-4’s 5×10⁶-cycle fatigue test without drift.
3. R=0.1 Load Control: Advanced closed-loop system maintains stress ratios during dynamic loading.
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 15+ 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: 2,300 N peak force capacity with programmable load ratios (R=0.1–10).
• Triaxial Loading System: Simultaneous axial/torsional/shear loading (50 Nm max torque).
• Dynamic Load Control: 1–30 Hz frequency range with programmable waveforms (sine, square, random, custom).
