Joint Fatigue Testing Machine

Description:

The Joint Fatigue Testing Machine is widely used in biotribology research for artificial joint replacement materials, including acetabular cup components, femoral heads, menisci, structural materials for tibial components, and lubricant materials for knee and hip joints.

Features:

This Joint Fatigue Testing Machine can simulate the following motion curves:

(1) Figure-eight (butterfly) as shown

(2) Clockwise/counterclockwise ellipse (continuous motion)

(3) Linear reciprocation (non-continuous)

(4) Angular reciprocation (clockwise, counterclockwise)

(5) Circle (clockwise, counterclockwise)

(6) Square (clockwise, counterclockwise)

Usage:

The friction-corrosion module of the Joint Fatigue Testing Machine is a customizable system that can include one or multiple corrosion bath positions, with up to six baths, providing a unique measurement method for typical durability tests in biotribology.

Capable of continuous operation for 5 million cycles.

All corrosion bath positions are programmable for multi-directional simultaneous operation.

Elliptical, circular, figure-eight, square (clockwise or counterclockwise)

Linear and angular reciprocation

Simple pin or ball (metal, ceramic, or polymer), disk (metal, ceramic, or polymer)

Each station has an independent pin/disk rotating on its corresponding axis (optional)

Sliding speed 0.1 m/s

Independent load control per corrosion bath position up to 400 N

Multiple corrosion bath positions operating together, up to 3000 N* (optional)

Temperature measurement module (optional)

Independent friction force measurement per corrosion bath position (optional)

Independent hose hydraulic pump circulation (optional)

Applications:

Various types of artificial joints

ASTM F732

ISO 14242-1 (load profile)

Standard Sample Dimensions:

The instrument's standard sample holder dimensions are as follows:

Pin: 8 mm, 10 mm, and 12 mm diameter, 12 mm length
