Material plane contact friction performance test device

Abstract

The utility model relates to a testing device for plane contact friction performance of materials. In order to overcome the lack of comprehensive simulation conditions in the existing pin-on-disc material friction and wear performance test, and the inability to carry out plane full contact wear test on large-area samples, the sample of the present invention is fixedly installed on the side of the sample base, and the wear The sample is fixedly installed on the side of the grinding sample base; the sample and the grinding sample are installed facing each other, and the contact plane between the sample and the grinding sample is perpendicular to the horizontal plane; The axis of the axis is perpendicular to the plane of the grinding sample, and the end of the force axis protruding from the base of the grinding sample is a spherical surface. Its beneficial effect is that the design is reasonable and easy to operate. Under the condition of sample plane contact, it simulates the actual friction and wear conditions of the material plane, accurately measures the friction force of the material when it is moving, and reflects the friction coefficient during the material friction process in real time to characterize the material friction. wear performance.
