Abstract

The invention discloses a constant-speed friction and wear experiment data measurement method, and the method comprises the following steps: step 1, manufacturing an experiment material into a fixed test piece and a moving test piece according to the specification of an experiment, and respectively installing the fixed test piece and the moving test piece on a fixed clamp and a moving clamp of a testing machine; step 2, setting test parameters such as applied load, temperature, time and the like according to the test requirements; step 3, setting the motion speed of the constant-speed friction testing machine, so that the motion frequency f1 of the moving clamp of the constant-speed friction testing machine and the sampling frequency f2 of a sensor of the constant-speed friction testing machine are in a multiple relation; step 4, starting the constant-speed friction testing machine to carry out a friction and wear experiment, and collecting experiment data through the sensor; and step 5, analyzing the friction and wear performance of the test piece according to the acquired data. According to the method, the relative position of the test piece is fixed at the data acquisition moment, so that the problem of inaccurate detection result caused by processing errors or installation errors is solved, and the detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of friction and wear detection, in particular to a constant-speed friction and wear experimental data measurement method. Background technique [0002] Tribology is a science based on experimental research. According to the tribological system theory, when conducting tribological tests, similar friction pairs and friction test conditions should be selected according to the actual friction system. The friction phenomenon is very complex and is a comprehensive performance of various factors. Therefore, in the process of tribological test research, in order to draw as reliable a conclusion as possible, the test conditions must be strictly controlled to avoid interference factors other than test variables. However, some errors are unavoidable and will always interfere with the test results, such as the shape and position tolerances formed by the machining errors when manufacturing the friction pair test samples,...
