Microcomputer controlled three-axis fatigue testing machine

HYYW-5000E three-axis fatigue testing machine adopts a servo motor + weight combination loading technology solution to directly

The linear servo actuator serves as the main power source and cooperates with the precision weight system to achieve high-precision and high-stability axial load accelerating.

load.The system integrates a three-axis independent control unit, which can simultaneously realize axial loading, tangential loading and rotational torque loading.

The coordinated control fully meets the requirements for mechanical performance evaluation of movable padded knee prostheses under cyclic loading.

This equipment is specially designed for medical device testing institutions, scientific research institutes and artificial joint production enterprises, and is widely used in

Dynamic fatigue performance testing, friction and wear assessment and reliability verification of orthopedic implants.The equipment adopts oil-free electric power

Servo actuator drive technology makes the operation process clean and environmentally friendly, without the need for auxiliary facilities such as hydraulic oil and cooling water, and is easy to install.

Convenient and low maintenance cost.This series of test systems absorbed internationally advanced electric servo drive technology during the development process.

Designed based on the actual usage conditions of domestic users, the performance of the whole machine is equivalent to the technical level of international advanced products.
