Frequently Asked Questions: Servo Hydraulic Dynamic & Static Testing Machine
1. What is a Servo Hydraulic Universal Testing Machine (UTM) used for?
The PWS Series Servo Hydraulic UTM is a versatile testing instrument designed for both dynamic and static mechanical testing. It is primarily used to evaluate the strength, durability, and fatigue life of materials such as metals, composites, plastics, and structural components. Common tests include tensile, compression, low-cycle fatigue, and fracture mechanics.
2. Can this machine perform both static and dynamic fatigue tests?
Yes. The PWS series is specifically engineered for dual-purpose testing. It handles static tests (constant load or deformation) and dynamic tests (high-frequency cyclic loading). This makes it ideal for simulating real-world stress on aerospace, automotive, and civil engineering components.
3. What are the maximum load capacities available for the PWS series?
We offer several models to suit different testing requirements, with maximum static and dynamic force capacities including:
4. What types of waveforms can the dynamic controller produce?
The integrated dynamic controller and software support a wide variety of test waveforms, including:
5. What materials can be tested with this hydraulic UTM?
The machine is compatible with a vast range of materials and components, including:
-
Metals: Steel bars, metal sheets, and alloys.
-
Polymers: Rubbers, plastics, and composite materials.
-
Components: Springs, power cables, and structural fasteners. With optional high/low-temperature chambers, you can also perform mechanical testing under extreme environmental conditions.
6. How accurate are the measurement results?
The PWS series provides high-precision data suitable for R&D and quality control:
-
Load Static Accuracy: ≤±0.5% of indicated value.
-
Load Dynamic Accuracy: ≤±1.0% of indicated value.
-
Displacement Accuracy: ±0.5% FS.
7. What safety features are built into the system?
Safety is a priority for unmanned or long-duration fatigue testing. The system includes:
-
Software Protection: User-defined upper/lower limits for load and displacement.
-
Hardware Protection: Motor phase loss and overcurrent protection, oil temperature interlocks, filter blockage alarms, and an emergency stop system.
8. Does the machine come with specialised software?
Yes, the machine includes a core multi-channel closed-loop control module and intuitive experimental software. The software allows for real-time data acquisition, automated analysis, and custom test editing to meet specific international standards (ISO, ASTM, etc.).
9. Which industries typically use the PWS Dynamic Testing Machine?
This equipment is a standard in industries requiring rigorous material validation, including:
-
Aerospace & Aviation (Fatigue crack propagation)
-
Automotive & Transportation (Component durability)
-
Metallurgy & Construction (Tensile and yield strength)
-
Research & Universities (Material science and fracture mechanics)
10. Is the testing space customizable?
Yes. While the standard vertical test space is 1000mm and the space between columns is 500mm, both dimensions can be customized to accommodate larger structural components or specialized fixtures.
