Multifunctional Hip Joint Wear Test System

Model: UTDS-M03, ISO 14242-1, ISO 14242-2

UTDS-M03 Multifunctional Joint Wear Test System is design and produced fully according the ISO 14243-1-2012 Surgical Implants. Wear and tear of total knee prosthesis. Part 1.; ISO 14243-2-2016 Wear and tear of total knee prostheses for surgical implants.; ISO 14243-3-2014 Surgical implants.Wear and tear of total knee prostheses.Part 3. 

For the test of Knee/hip abrasion, are widely used in artificial joint replacement materials, and are used to replace structural materials such as acetabular cup elements, femoral head, meniscus, tibia, etc., as well as lubricant materials for knee and hip joints, respectively.

At the same time, it has the function of abrasion test of positive shoulder joint and reverse shoulder joint and knee joint restraint test function, which is very comprehensive, and has strong customization and scalability, and will continue to expand more joint wear and static test functions.


General Introduction

UTDS-M03 Multifunctional Joint Wear Test System is design and produced fully according the ISO 14243-1-2012 Surgical Implants. Wear and tear of total knee prosthesis. Part 1.; ISO 14243-2-2016 Wear and tear of total knee prostheses for surgical implants.; ISO 14243-3-2014 Surgical implants.Wear and tear of total knee prostheses.Part 3. 

For the test of Knee/hip abrasion, are widely used in artificial joint replacement materials, and are used to replace structural materials such as acetabular cup elements, femoral head, meniscus, tibia, etc., as well as lubricant materials for knee and hip joints, respectively.

At the same time, it has the function of abrasion test of positive shoulder joint and reverse shoulder joint and knee joint restraint test function, which is very comprehensive, and has strong customization and scalability, and will continue to expand more joint wear and static test functions. Table 1-1 shows the main technical indicators of the product.

ISO 14242-1 - Implants for surgery — Wear of total hip-joint prostheses — Part 1: Loading and displacement parameters for wear-testing machines and corresponding environmental conditions for test
ISO 14242-1:2014 specifies the relative angular movement between articulating components, the pattern of the applied force, the speed and duration of testing, the sample configuration, and the test environment to be used for the wear testing of total hip-joint prostheses.

Multifunctional Hip Joint Wear Test System


Key Features

  • Main features
  • Actuator
  • Main Test
  • Wear Testing:

1. The operating principle of multi-axis direct drive motor, mature technology and high reliability;

2. Low failure rate, no need to replace parts regularly;

3. Six degrees of freedom per station, good flexibility and strong scalability;

4. It has the function of independent control of 3+1 stations, 3 experimental stations and 1 control station;

5. Control wear mode with both load and displacement;

6. Equipped with high-strength water bladder, 50W circle does not break or leak;

7. Mains AC 220v power supply, low operating cost;

8. Low noise, no oil pollution;

1), Servo liner actuator is the key part in this testing machine, the test output load through this actuator; with United Test technology self design, the actuator internally intall on the top side of frame, consist of actuator, servo motor, servo driving sytem, and load cell.

2), Servo liner actuator frequency limitation position have relief area, avoid the damage of out control.

3), Liner sensor with USA Schaevitz company LVDT, move smoothly, piston rod made by extra-fine process, surface chrome-plated polishing to Rα0.4u.

4), Between load cell and clamper connection, push-pull rod and clamper position have specialized gap elimination device, then improve the dynamic response ability.

1, Knee abrasion test

2, Hip abrasion test

3, Shoulder abrasion test

4, Anti-shoulder abrasion tes


UnitedTest ISO 14242-1 Multifunctional Hip Joint Wear Test System simulators, multi-station hip and knee simulators, assess the wear behavior of your implant materials, ensuring optimal performance over time.
