A brief analysis of the characteristics of the ring stiffness testing machine.

A brief analysis of the characteristics of the ring stiffness testing machine is provided below.

1. Performance characteristics of the servo controller of the ring stiffness testing machine:

1) This controller uses a high-speed ARM chip as the main control chip, possessing high computing speed and data processing capabilities. It can quickly complete the entire control process from data acquisition, PID calculation, Ethernet communication to output control, thereby achieving precise closed-loop control of the testing machine;

2) Input channels:

a) It has three analog input channels: one for load, one for electronic extensometer, and one for expansion. All three channels use independent 24-bit A/D converters for high-precision data sampling, with an effective internal code of up to 400,000;

b) Up to 15 segments of linear compensation and correction functions, greatly improving the measurement range and accuracy of the sensors;

3) Control functions of the ring stiffness testing machine:

a) It adopts a PID control strategy to achieve closed-loop control of the load, realizing functions such as constant speed loading and unloading, and load holding;

b) It adopts a PID control strategy to achieve closed-loop control of the displacement, realizing functions such as constant speed displacement and displacement holding;

c. A PID control strategy is employed to achieve closed-loop control of deformation, realizing functions such as constant-speed deformation and deformation holding;

4) Communication Interface: A 100MHz Ethernet communication interface is used to achieve high-speed data communication with a PC, enabling real-time uploading of acquired data and real-time distribution of control commands, thereby achieving real-time PC control of the testing machine.

2. Features of the Ring Stiffness Testing Machine's Control Software:

1) The control software adopts a brand-new software style, featuring a beautiful and user-friendly interface, powerful functions, and simple operation;

2) It can configure any number of display frames, with configurable channels, units, and decimal places, and can be arranged horizontally or vertically;

3) The number of test curve frames can be selected arbitrarily from 1 to 3, and multiple curve frame layouts can be switched arbitrarily. The coordinates of the curve frames can be arbitrarily selected, and the test curves can be partially magnified and saved as image files;

4) It can be configured with multiple force sensors and multiple deformation sensors, which users can switch between as needed;

5) It has three levels of management permissions: manufacturer's commissioning personnel, administrator, and testing personnel;

6) Adopts an open standard testing configuration mode. The standard software includes over 30 testing standards such as GB/T228.1-2010, GB/T1040-2008, and GB/T528-1998. Users can easily add, delete, or modify testing standards, and the control steps can be freely edited according to testing requirements.

7) At the end of the ring stiffness testing machine test, it can automatically calculate and save test results data, such as maximum force, tensile strength, yield strength, and non-proportional extension strength, and display characteristic points on the test curve.

8) The software has test analysis functions, which can analyze the data of completed test results and overlay and compare multiple test curves within a set.

9) Uses a standard database to manage test data and provides a network data interface.

10) Users can choose our company's self-developed SingoReport reporting system to edit and print reports, or they can use Excel spreadsheets to edit and print reports.

3. Safety Protection of the Ring Stiffness Testing Machine:

1) The servo motor controller will alarm and stop when the servo motor experiences overcurrent, overvoltage, or overspeed.

2) Limit protection: The moving crossbeam will automatically stop moving when it touches the upper or lower limit.

3) Automatic shutdown: The moving crossbeam will automatically stop moving after the sample breaks.

4) Overload protection: The moving crossbeam will automatically stop moving when the load exceeds 2-5% of the maximum value.
