The KY8000 series microcomputer controlled electronic ring stiffness tensile testing machine is a new type of material testing machine that combines electronic technology with mechanical transmission. It has a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity in measuring and controlling load, deformation, and displacement. It can also perform automatic control tests of constant speed loading and constant speed displacement, and has functions of low cycle load cycle, deformation cycle, and displacement cycle.

Main functions:

This series of models is mainly suitable for various pipe ring stiffness testing tests, meeting a series of relevant testing standards. Electronic testing machine fixtures can be added to achieve electronic testing machine related functions.

Main features:

1: Adopting a high-speed DSP platform, its high integration, powerful control, data processing capabilities, and high reliability are unmatched by testing machines using other processors.

2: A fully digital, three loop (force, deformation, displacement) control system based on neuron adaptive PID algorithm is adopted to achieve fully digital three loop control of force, deformation, and displacement. The control loops can be automatically switched between, and a smooth transition without impact can be achieved when switching between different modes.

3: It can control and maintain the rate of experimental force, deformation, displacement, etc.

4: Online identification of closed-loop control parameters.

5: High precision 24 bit data acquisition system, high resolution, expandable 8-channel AD acquisition.

6： USB1.1 communication, with a communication rate of 12Mb/s, using full speed mode and batch transfer method.

7: The system board adopts a 4-layer PCB special anti-interference wiring method, which has strong anti-interference ability.

8: Except for the power interface, all other interfaces use standard USB interfaces, which are plug and play interfaces that can achieve hot plugging and have plug and play functionality. The interface characteristics can be set online by software. Make the layout of each interface neat and reasonable, and easy to plug and unplug.

9: The entire control system has high cost-effectiveness and high reliability.

10: Adopting microcomputer control throughout the entire testing process, real-time dynamic display of load values, displacement values, deformation values, testing speed, and testing curves.

11: Using a microcomputer for data processing and analysis, the experimental results can be automatically saved. After the experiment is completed, the experimental curve can be retrieved again, and the experimental process can be reproduced by traversing the curve, or curve comparison and amplification can be performed.

12: The experimental software on the Windows platform, which is entirely in Chinese, has strong data and graphics processing capabilities and can print complete experimental reports and curves in real time.

13: Equipped with comprehensive safety protection functions such as limit protection, overload protection, and emergency stop.
