What are the ways to test the friction properties of friction materials
The friction testing equipment is a friction testing machine, which can be used to test the friction coefficient, braking torque and wear performance of friction materials under different working conditions (different temperatures, speeds, pressures). Friction testing machines are divided into the following types:
(1) Sample friction testing machine
This kind of testing machine is to test the friction coefficient and wear performance of the samples (samples) taken from the finished products (brake pads or clutch facings) according to the specified requirements, for example: my country currently implements the GB5763-2008 and GB5764-2008 standards The constant-speed friction testing machine, the Chase friction testing machine that implements the SAEJ661 test specification in North America, the FAST testing machine, the MM-1000 testing machine and so on.
The advantage of the sample friction tester is that the test is simple, convenient and fast, but the experimental conditions are far from the actual working conditions when the friction plate is working in terms of simulation. It is mainly used for factory production quality control and formulation research, and new product development. The preliminary research stage.
