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

Dual-Environment Testing: Integrated water bath chamber (37°C ±0.5°C) simulates in-vivo conditions for clinically relevant data.

Precision Fatigue Analysis: 0.01Hz–50Hz frequency range captures both low-cycle and high-cycle fatigue behavior.

Automated SOP Execution: Pre-loaded test protocols for YY/T 1429 and ISO 16402 ensure regulatory compliance.

Real-Time Fatigue Monitoring: Live S-N curve plotting and crack propagation detection via acoustic emission sensors.

Modular Specimen Clamping: Quick-release fixtures accommodate rectangular beam specimens (2×4×30mm to 6×12×60mm).

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.
