Bone Cement Four-Point Bending Fatigue Tester

Standard 

• YY/T 1429 (China): Specifies four-point bending fatigue tests for acrylic resin bone cements under quasi-static and cyclic loading.
• ISO 16402 (International): Defines protocols for determining the fatigue life of bone cements in simulated physiological environments.
• Additional alignment with ASTM F2118 for constant load fatigue testing of polymer-based bone cements.

Product Advantages

1. Dual-Environment Testing: Integrated water bath chamber (37°C ±0.5°C) simulates in-vivo conditions for clinically relevant data.
2. Precision Fatigue Analysis: 0.01Hz–50Hz frequency range captures both low-cycle and high-cycle fatigue behavior.
3. Automated SOP Execution: Pre-loaded test protocols for YY/T 1429 and ISO 16402 ensure regulatory compliance.
4. Real-Time Fatigue Monitoring: Live S-N curve plotting and crack propagation detection via acoustic emission sensors.
5. Modular Specimen Clamping: Quick-release fixtures accommodate rectangular beam specimens (2×4×30mm to 6×12×60mm).
6. Data Integrity: Blockchain-timestamped results prevent tampering and simplify audit processes.

Product Features

• Four-Point Bending Configuration: 30–100mm span adjustable for standardized (ISO) or custom specimen geometries.
• Electrohydraulic Actuator: Delivers sinusoidal, square, or random vibration waveforms up to 1kN force.
• Thermostatic Water Bath: Dual-zone temperature control (15–50°C) with anti-evaporation lid system.
• High-Speed Data Acquisition: 16-bit resolution at 10kHz sampling rate captures transient failure events.
• AI-Assisted Analytics: Machine learning algorithms predict fatigue life from partial test data.
• Safety Interlock System: Emergency stop, over-temperature protection, and breakaway specimen holders.
