Description

technical field [0001] The invention belongs to the technical field of mechanical detection, in particular to a multifunctional weight-loaded friction and wear testing machine. Background technique [0002] In the mechanical industry, friction and wear are the main causes of energy consumption and material failure. The purpose of the friction and wear experiment is to correctly evaluate the influence of various factors on the friction and wear properties of materials, analyze the phenomenon of friction and wear and its essence, so as to determine the optimal parameters for the friction pair components in engineering applications. In-depth study of the friction and wear mechanism of the friction pair under different conditions, and then control the friction and wear process, will help to improve the service life, stability and reliability of the equipment. Therefore, it is very important to effectively and accurately evaluate the friction and wear characteristics of motion me...
