Three Main Uses
Series of microcomputer-controlled electro-hydraulic servo universal testing machines, hereinafter referred to as testing machines, are mainly used Mechanical property tests on tensile, compression, bending, shear and other mechanical properties of standard parts of metallic and non-metallic product parts and structural parts. If the testing machine is equipped with an environmental device, it can also perform tensile and compression tests on materials in that environment. For example, high temperature and low temperature tensile and compression tests. This machine is an ideal testing instrument for mechanical laboratories and structural laboratories of industrial and mining enterprises, construction material inspection centers, water conservancy, hydropower, highways and bridges, scientific research institutes, colleges and universities.
Four functional features
This machine combines powerful special measurement and control software, which can automatically measure, automatically control, automatically zero, automatically calibrate, and continuously measure the whole process without binning. It has the characteristics of data collection, processing, curve drawing and curve report printing. Adopting advanced fuzzy control algorithms, it can realize three closed-loop controls such as equal-rate loading, equal-rate deformation, equal-rate displacement closed-loop control, and automatic constant load, constant displacement, and constant deformation. The three closed-loop control methods can be manually or programmed during the test process. The switch can automatically calculate various mechanical property indicators of the material: maximum load, tensile strength, compressive strength, bending strength, shear strength, elastic modulus, elongation, yield strength, non-proportional extension strength, total extension strength, etc., and can be tested according to various test methods and Standards conduct tests and provide various testing data.

It adopts advanced fuzzy control algorithms and can Three closed-loop controls including equal-rate loading, equal-rate deformation, equal-rate displacement closed-loop control, and automatic constant load, constant displacement, and constant deformation are realized. The three closed-loop control modes can be switched manually or program-controlled during the test process, and various parameters of the material can be automatically calculated. Mechanical property indicators: Maximum load, tensile strength, compression strength, bending strength, shear strength, elastic modulus, elongation, yield strength, non-proportional extension strength, total extension strength, etc., can be tested and provide various testing data according to various test methods and standards. .
The test process uses the computer to automatically collect, control and process the data of the test process, and the screen can dynamically display and switch to display various test curves. The stress strain curve, force elongation curve, force time curve, deformation time curve, displacement time curve can be drawn to achieve multiple color curves for easy comparison. After the test is completed, any segment on the test curve can be selected for regional enlargement analysis, which can be performed individually or in groups. Sample test. It has many functions such as automatic overload protection.
