Content

The Total Knee Prosthesis Wear Testing Machine is a specialized testing device designed to evaluate the wear performance and durability of knee joint implants. It simulates physiological motions and loads experienced by knee prostheses during walking or other activities, measuring material wear, component deformation, and overall implant longevity under repeated cyclic loading conditions.

Standards

(1)YY/T 0651.2

(2) ISO 14243-1

These standards specify the testing requirements for total knee prostheses on a wear simulator equipped with axial load control, flexion/extension angle motion control, anterior-posterior displacement control, and tibial rotation motion control. The standards define the relative flexion/extension angular motion between joint components, loading protocols, test speeds and durations, specimen assembly, and test environment requirements.

Product Features

Next-generation fatigue testing system driven by a large electromagnetic motor;

Direct-drive electromagnetic motor provides stable operation with high repeatability, ensuring precise control of force and displacement;

Integrated electromagnetic actuator features low friction and high repeatability, with rapid system response and high speed;

Capable of performing tensile, compressive, bending, shear, creep, and relaxation tests;

Meets modern material testing requirements for high precision, high frequency, high stability, and durability;

Oil-free, seal-free, maintenance-free design with long service life, high integration, easy installation, and small footprint;

Wide range of fixtures and accessories available.
