Wear Resistance Tester for Total Hip Joint Prostheses

Standard

YY/T 0651.1-2016 (China): Specifies wear testing parameters for total hip prostheses, including angular motion, loading modes, and environmental conditions.

ISO 14242-1:2014 (International): Defines protocols for simulating physiological loading and kinematics during hip joint wear testing.

ASTM F3047M-15: Additional compliance for advanced testing scenarios including edge loading and micro-separation.

Product Advantages

Triaxial Motion Simulation: Replicates full physiological motion profiles (flexion/extension ±100°, abduction/adduction ±30°, internal/external rotation ±40°).

Dynamic Load Control: Dual-peak loading up to 4.500 N with 0.1% force accuracy.

Biorelevant Environment: Temperature-controlled (37±2°C) lubrication bath with 30±2 g/L protein concentration.

Extended Durability: Capable of 5+ million cycle testing with <0.5% drift in calibration.

Automated Compliance: Pre-programmed ISO/YYT test protocols with real-time data validation.

Modular Design: Six-station configuration allows parallel testing of multiple specimens.

Product Features

Electrohydraulic Actuation: Six independent servo-hydraulic actuators for precise motion control.

3D Force/Torque Sensors: Multi-axis sensors measure axial forces and torsional moments simultaneously.

Temperature-Controlled Bath: Recirculating lubrication system with protein concentration monitoring.

High-Resolution Imaging: Optional integration with micro-CT systems for in-situ wear analysis.

AI-Powered Analytics: Machine learning algorithms predict wear rates from initial test cycles.

Safety System: Emergency stop, over-pressure relief, and laser-based specimen breakage detection.
