Hydraulic universal testing machine operation

The proper use of a hydraulic universal testing machine is crucial for ensuring the accuracy and reliability of the entire testing process. Following the correct operating procedures not only enhances test results but also helps in maintaining the equipment, preventing damage caused by improper handling. 1. **Pre-test Information Input** Before starting any test, it's essential to input all necessary data into the system. This step ensures that the machine operates according to the required specifications and parameters. 2. **Test Operation** The actual testing process involves several key steps: - **Sample Installation**: Securely place the specimen into the testing machine, ensuring it is properly aligned. - **Test Setup**: Configure the test parameters such as load range, speed, and displacement based on the material being tested. - **Start the Test**: Initiate the test by pressing the start button. The machine will apply the specified load or deformation to the sample. - **End the Test**: Once the test is complete, stop the machine and record the data. 3. **Data Storage and Curve Analysis** After the test, save the collected data and analyze the resulting stress-strain curve. This visual representation helps in understanding the mechanical behavior of the material under test. 4. **Generate the Test Report** Compile all the relevant information, including test parameters, results, and analysis, into a comprehensive report for documentation or further review. When testing metal materials, the standard test methods provided by the system are typically for reference only. Users should consult the latest national standards to determine the appropriate control method and speed for their specific material. 1. After launching the main program interface, the first step is to set up the required information. Click the "Set" shortcut button to open the "Settings Window" and configure the options accordingly. 2. In the data options section of the test control panel, select the appropriate test standard and sample parameter settings. Click to enter the sample data, and input details such as the sample number, original dimensions, and initial moment of inertia. By carefully following these steps, users can ensure accurate and consistent test results while maintaining the longevity of the hydraulic universal testing machine.
