Abstract

The invention provides a multifunctional vacuum friction and wear testing machine, which not only can simulate special environmental atmospheres such as vacuum, radiation and corrosion, but also can conduct tribology tests in a relatively wide speed and load range by using various contact manners (ball-disc and pin-disc). The multifunctional vacuum friction and wear testing machine mainly comprises a vacuum system, a friction and wear system, a power transmission system, a control system, and the like, wherein the friction and wear system comprises a lever structure (22) used for fixing a test sample fixture (20) and capable of freely rotating in a horizontal direction and a vertical direction; the lever structure (22) comprises a cantilever beam (18) and a vertical arm (23) which are arranged in a perpendicular manner; the cantilever beam (18) is connected with the vertical arm (23) through a two degree of freedom bearing structure (17); positions of the cantilever beam (18) and the vertical arm (23) can be adjusted in the horizontal direction and the vertical direction through the control of a manipulator (15) and a hand wheel structure (13), so that the test sample fixture (20) can accurately move within two degrees of freedom; and a temperature sensor (2) and a pressure sensor (3) are mounted on the test sample fixture (20), so as to detect / monitor friction coefficients and temperature variations during the tribology tests.

Description

technical field [0001] The invention belongs to the field of material and device performance testing, and in particular relates to a multifunctional vacuum friction and wear testing machine capable of simulating the effect of space environment factors (such as high vacuum environment) and testing the performance of friction materials and devices. Background technique [0002] With the development of high technology such as aerospace, many equipment such as spacecraft are operating in a high vacuum environment (10 -5 Pa~10 -7 Pa level), the vacuum environment will bring special tribological problems. For example, lack of oxygen and other atmospheric reactants in the vacuum, the oxide film on the metal surface is quickly removed during the friction process, and it is difficult to form a new oxide film. Therefore, the friction surface is quickly in a "bare" state, and the fresh metal surface Severe adhesion occurs due to direct contact between them; there is no diffusion and ...
