The invention belongs to the technical field of tribology of mechanical engineering, particularly relates to a multi-mode friction wear test device and method, and solves the problems of function limitation and complex operation of a friction wear test device in the prior art. According to the technical scheme, the method comprises the following steps: clamping a ball sample / rolling sample on a clamp, and clamping a plane sample by using a plane sample clamp; controlling the plane sample to move up and down through the lifting platform to enable the ball sample / rolling sample to contact with the plane sample; and enabling the motor to drive the ball sample / rolling sample to reciprocate up and down according to set parameters, and performing a reciprocating impact / sliding / rolling test, a two-mode composite test and a three-mode composite test on the plane sample. The three-dimensional force sensor measures the force borne by the plane sample clamp, and a friction coefficient-cycle indexcurve is obtained through analysis. The test device and method can be used for carrying out rigidity-adjustable impact, sliding and rolling multi-mode friction and wear tests, are simple to operate,can save the test cost, and are suitable for research of composite friction.

Description

technical field [0001] The invention belongs to the technical field of tribology of mechanical engineering, and in particular relates to a multi-mode friction and wear test device and method. Background technique [0002] The wear of parts directly affects the service life of the equipment, and the friction noise pollutes the environment. In-depth study of the wear and deformation mechanism of large-deformation friction pairs, and reducing the wear of friction pairs as much as possible is an urgent problem to be solved in engineering applications. In actual application conditions, the relative motion between the friction pairs is very complicated, and the resulting wear is often the result of the combined action of various wear forms. Impact and sliding wear are relatively common wear forms, and in some special occasions such as shield tunneling The hob and the like are even more complex with the sliding motion of the parts. Impact-sliding composite friction is a relativel...
