Femoral Condyles Components Fatigue Performance Tester
Standard
- ASTM WK51649: Specifies fatigue testing protocols for metallic femoral components in total knee arthroplasty, including F-N curve generation and 10⁷-cycle endurance verification.
- ISO 14879-1: Additional compliance for fatigue testing of total knee joint prostheses.
- Adaptive Protocols: Customizable for emerging standards in additive-manufactured and coated implant evaluation.
Product Advantages
- Ultra-Precision Loading: Electromagnetic actuator delivers ±0.05% force accuracy with 0.001N resolution.
- 10 Million Cycle Endurance: Proven capability to complete ASTM WK51649’s 10⁷-cycle fatigue test without calibration drift.
- Dynamic Load Control: Advanced closed-loop system maintains specified stress ratios during sinusoidal/random loading.
- 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 Actuator: 5,000 N peak force capacity with programmable load ratios (R=0.1–10).
- Triaxial Loading System: Simultaneous axial/torsional/shear loading (30 Nm max torque).
- Dynamic Load Control: 0.1–30 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.
