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.
