What is a hydraulic universal testing machine?
Hydraulic universal testing machine is a kind of equipment widely used in testing the mechanical properties of materials. It is mainly used to measure the tensile, compression, bending, shear and other mechanical properties of metals, non-metals, composite materials, etc. under different conditions. Its core principle is to apply high-precision loads through a hydraulic system, combined with sensors and data acquisition systems, to achieve precise measurement of material properties.
The following are the core components and functions of a hydraulic universal testing machine:
| components | Function description |
|---|---|
| Hydraulic system | Provide a stable high-pressure oil source to drive the piston movement to apply load |
| Loading frame | Supports the specimen and transmits loads, usually made of high-strength steel |
| control system | Adjust loading rate, holding load or displacement, support multiple test modes |
| Measurement system | The sensor collects data such as force value and deformation in real time with an accuracy of ±0.5%. |
| Fixture device | Adapt to different sample shapes (such as plates, bars) to ensure test stability |
Popular application areas (industry focus in the past 10 days)
According to recent industry data analysis, the demand for hydraulic universal testing machines has increased significantly in the following areas:
| Application areas | Typical test items | technology trends |
|---|---|---|
| New energy vehicles | Battery case compression test, aluminum alloy component strength verification | The demand for high and low temperature environment simulation testing is rising |
| Aerospace | Shear test of titanium alloy fasteners, interlaminar strength of composite materials | Increase in procurement of large-tonnage equipment above 1000kN |
| Building materials | Repeated loading test of seismic steel bars, compressive strength of concrete | Popularization of automated data collection systems |

| MTS 322 | 250 | Level 0.1 | 500×500 | 500,000+ |
Precautions when purchasing
According to recent user survey data, you need to focus on the following when purchasing:
1.Test standards compatibility: The equipment needs to support the latest standards such as GB/T 228.1-2021 and ISO 6892-1
2.Extended functions: 67% of users tend to choose the configuration with video extensometer
3.After-sales service: The manufacturer's response time should be ≤24 hours, and the guarantee of spare parts supply is a key indicator.
Industry development trends
Recent technical trends show:
• The penetration rate of intelligent hydraulic systems has increased by 18% annually, supporting APP remote monitoring
• 5G+ test machine IoT solution started piloting in key laboratories
• The demand for environmentally friendly hydraulic oil is rising, and the market share of biodegradable products reaches 27%
