PWS-2 Type Microcomputer-Controlled Electronic Servo Magneto-Rheological Damping Tester

I. Overview

The PWS-2 type microcomputer-controlled electronic servo magnetorheological damper comprehensive tester is composed of the main unit, control system, computer and software system, and test accessories. It is mainly used for demonstrating and fatigue testing of magnetorheological dampers for high-end cars, and can also be used for demonstrating and fatigue life testing of筒式减振器 on motor vehicles such as cars, motorcycles, and armored vehicles.

2. Can be used for various small-load fatigue life tests and static mechanical property tests on metals and non-metallic materials when combined with corresponding auxiliary testing equipment.

3. The machine employs electronic servo control technology with a closed-loop system, featuring a rational and simple structure, accurate and convenient adjustment of the test space and stroke, easy and reliable fixture of specimens, and stable operation for easy maintenance and upkeep.

4. This machine is centered around electronic servo control technology, utilizing the latest international direct-acting servo technology. It features no need for hydraulic power source, no cooling equipment, energy-saving, and is a technical product in the small-tonnage fatigue testing field.
