Test Method

Preparation

Check the instrument: Make sure the power connection of the friction coefficient tester is stable, check the integrity of all components, especially the measurement sensor and the drive system. Make sure that there is no damage or abnormality in the equipment.

Clean the instrument: Clean the working surface of the friction tester to ensure that there is no oil, dust and other impurities.

Prepare the specimen: Select the appropriate specimen material according to the test requirements. The specimen should be flat and clean to avoid dust or oil to affect the measurement of friction.

Prepare calibration tools: Prepare standard weights, standard friction plates, calibration certificates and other necessary calibration tools and documents.

Specimen Installation

Fixing the specimen: Fix a specimen with the test surface upward and flat on the horizontal test bench. The specimen should be parallel to the length of the test bench.

Mounting the slider: Place the other specimen with the test surface down, wrap it around the slider, and secure the specimen with adhesive tape on the front and upper surfaces of the slider.

Placement of the slider: Place the fixed specimen slider in the center of the first specimen without impact, and make the test direction of the two specimens parallel to the direction of the slider and the force measurement system is not subject to force.

Setting test parameters

Setting parameters: In the control panel of the tester, set the relevant parameters, such as load, speed, test time, etc. These parameters need to be set according to the actual test requirements. These parameters need to be adjusted according to the actual test requirements to ensure compliance with the experimental design specifications.

Calibrate the instrument: Before testing, the equipment needs to be calibrated to ensure the accuracy of the measurement results. The calibration process includes adjusting the level of the frame, setting the test speed, calibrating the mass of the slider and other steps.

Execute the test

Start the test: After confirming that all settings are correct, start the friction tester and begin the testing process. During the test, the instrument will automatically record the friction force, displacement and time data, and calculate the friction coefficient through the algorithm.

Record data: During the test, the instrument will automatically generate a data report, the operator needs to check the accuracy of the data, and analyze and summarize as needed. When recording the results, be sure to save all the original data for subsequent verification and review.

Data Analysis and Report Generation

Calculate Friction Coefficient: The formula for calculating the friction coefficient is usually the ratio of friction force to positive pressure. [...]  [...] 

Solution: This may be due to improper sample installation or changes in the testing environment. Recalibrate the instrument, make sure all parameters are set accurately, and adjust the temperature and humidity of the experimental environment if necessary to reduce the interference of external factors.
