Description

technical field [0001] The invention belongs to the technical field of material performance testing equipment, and in particular relates to a multi-working-condition ring block friction testing machine. Background technique [0002] The ring block friction testing machine is a device for testing the friction performance of materials. By processing the tested materials into friction test blocks and friction ring blocks, and conducting friction tests on the two, the friction performance parameters of the tested materials can be obtained. [0003] The existing general-purpose ring-block friction testing machine has a simple structure and can only perform a uniform-velocity friction test under a constant pressure. In actual production and life, the friction forms of various sliding parts are relatively complicated, such as plungers, bearings, rims and other components. In actual work, they will experience complex working conditions such as normal impact, braking, speed change, a...

Problems solved by technology

[0004] In order to study the influence of the above-mentioned complex working conditions on the friction performance of materials, the traditional method is to design a special friction testing machine separately according to the use environment of the tested parts. This kind of testing machine has a narrow application range and large limitations, so it cannot be popularized.
