The high-temperature fatigue testing machine is mainly used to simulate the fatigue performance of materials under alternating loads in high-temperature environments, and the following types of tests can be performed:
1.High-temperature fatigue test: By applying alternating loads in a high-temperature environment, the fatigue life and fatigue limit of a material under high-temperature conditions are evaluated.
2.Thermal expansion fatigue test: It is of great significance to evaluate the fatigue damage caused by thermal expansion of materials under high temperature conditions, which is of great significance to study the stability and life of materials in high temperature environments.
3.Pulsed thermal load fatigue test: Simulates the condition that the material is subjected to pulsed thermal load under high temperature operating conditions to evaluate the fatigue resistance of the material.
4.High-temperature tensile and fatigue test: Combines tensile and fatigue properties at high temperatures to comprehensively evaluate the load performance of materials in high temperature environments.
5.High-temperature low-cycle fatigue test: By applying low-cycle cyclic load in a high-temperature environment, the low-cycle fatigue performance of the material is studied, and the life of the material under actual working conditions is studied.
The above test types can help researchers fully understand the performance characteristics of materials in high-temperature environments, and provide important data support for material design, selection, and engineering applications.
So how to operate a high-temperature fatigue testing machine?
1.Sample preparation: First, prepare the material samples to be tested, and carry out the necessary processing and processing according to the test needs to ensure that the samples meet the requirements of the test standards.
2.Set test parameters: Set test parameters according to test requirements and sample characteristics, including temperature range, loading mode, amplitude, frequency, etc., to ensure that the test process meets the design requirements.
3.Install the sample: Install the sample into the loading system of the high-temperature fatigue testing machine to ensure that the connection between the sample and the testing machine is stable and can be subjected to normal force and heat.
4.Heating system start: Start the heating system of the high-temperature fatigue testing machine, gradually increase the set temperature to the high-temperature state required by the test, and start the test after maintaining stability.
5.Set the loading mode: according to the test requirements, set the loading mode in the test, which can be different loading modes such as constant amplitude load, sinusoidal load, pulse load, etc.
6.Running test: Start the high-temperature fatigue testing machine, start the fatigue test operation, load and unload according to the set parameters, and record the stress, strain and displacement data of the sample for subsequent analysis.
7.Data collection and analysis: real-time monitoring of sample changes during the test and collection of relevant data. At the end of the test, the data is analyzed and processed to evaluate the high-temperature fatigue performance of the material.
Through the above steps, the high-temperature fatigue testing machine can accurately evaluate the fatigue properties of materials in high-temperature environments, and provide an important reference for the design and application of new materials.
