Abstract

The invention relates to the technical field of friction coefficient testing, and discloses a friction coefficient testing device which comprises a test bed, a sliding block and a driving mechanism used for driving the sliding block to slide on the test bed. A first negative pressure cavity is formed in the test bed, a plurality of first suction holes communicated with the first negative pressure cavity are formed in the upper surface of the test bed, and a first air valve communicated with the first negative pressure cavity is further arranged on the test bed. According to the friction coefficient testing device, a sample is fixed in a negative pressure adsorption mode, the sample is prevented from wrinkling during testing, the testing accuracy is improved, the testing sample can be easily taken down without damage after testing is finished, and a test bed does not need to be cleaned.

Description

technical field [0001] The invention relates to the technical field of friction coefficient testing, in particular to a friction coefficient testing device. Background technique [0002] The coefficient of friction refers to the ratio of the friction force between two surfaces to the vertical force acting on one surface. It is related to the roughness of the surface and has nothing to do with the size of the contact area. According to the nature of motion, it can be divided into dynamic friction coefficient And the coefficient of static friction; sliding friction is produced by the relative sliding of two objects in contact with each other. [0003] At present, when testing the friction coefficient of polymer materials, the friction between two samples or the friction between the sample and other materials is usually used. Double-sided tape is used to fix the sample on the horizontal test bench, and use double-sided tape to fix the other sample. Products or other materials ...
