Computer Control Hydraulic Universal Testing Machine


1.Structure introduction:

It is mainly used to execute the tension, compression, bending, shearing etc. test for metal materials. Attached simple accessories and devices, it can be used to achieve many kinds of mechanical performances.

The oil cylinder is at the bottom of the load frame, tension space is at the upside of the load frame, compression and bending space is between lower crosshead and working table. The lower crosshead is driven by motor through decelerator, chain transmission device and screw pair, so realize the adjustment of testing space.

The machine adopts oil pressure transducer to measure load, use computer control &display load,

Brief introduction STC300 Control System

STC300 all-digital closed-loop control system has many advanced features and technological innovation, mainly reflected in:

● To achieve the test force, the specimen deformation, piston displacement and testing process, the four closed-loop control;

● Data acquisition system is composed of 4-way high-precision 24-bit A / D converter channels. The maximum resolution of up to 1 / 300000, full regardless of section;

● Use BB, AD, Xilinx and other original brand-name integrated device, all-digital design;

● Meet the PCI standard, computer and installation of automatic identification,;

● Electronic measurement systems without analog components such as potentiometers to ensure interchangeability for easy maintenance and replacement。



Brief introduction MaxTest software


MaxTestsoftware In line with GB228-87, GB228-2002 and other relevant provisions of more than 30 national standards

● Computer software system is highly integrated, stable performance, easy to adjust and so on. In real-time experimental data can be collected, the experimental realization of real-time dynamic display characteristic curves, test data files can be used with Access database or SQLserve way to save large databases to facilitate the sharing of resources to achieve customer and network management, and the user’s re-analysis. For a variety of user-defined reports word2000, the software can easily access to solve the different users or the same user at different times of the trial reports has different needs problems. The software can handle test force, displacement, time, raw data and the resulting derivative curve.。

● Protection function: This machine has two kinds of software and mechanical limit conservation, exceeds the maximum load can be automatically shut down the ratio of dynamic setting; with the over-current, over voltage, overload and other protection functions.。

● For the load channels can be automatically labeled and intuitively easy。


● Batch test can achieve the curves at different levels show。

● The software enables the user to customize the speed settings to adjust the speed of the computer. Can also achieve high-precision calibration of the speed at any time adjust the speed of section and coding 。


● Monitoring the testing process: the course of the experiment the test force, displacement, curves and other parameters can be realized real-time display 。

● Software rights management features classification: In order to improve software and data security, the software can set different passwords to protect data。

● The results reproduce features: the coexistence of trial operation is complete, after-hours, according to user needs at any time in the future to open and re-analysis of test data。

● According to the user can choose load ~ time 、load ~ displacement 、displacement ~ time curve to carry out testing and data display, storage, analysis and printing。

● Curve point by point traversal function: by mouse click on the force and deformation curves of the value of each point in order to achieve a variety of parameters.。


●The comparison function: You can simultaneously observe the number of experimental curves, multiple curves can be superimposed, local amplification to achieve the characteristics of the sample to be analysis。

● Power Interface: Force-channel interface and test software according to user needs with a variety of sensors, and can be calibrated, modify parameters and the normal test。

● Data sampling frequency: You can choose according to the user test requirements of high-speed sampling frequency。
