Abstract

The invention provides a fixture device for a rolling-sliding mixed friction test, and a use method of the fixture device. A set of block-ball-tray assembling device is formed by a pin sample, a ceramic ball sample and a tray sample; the radial size of the ceramic ball sample is adjusted by adjusting the aperture of a center hole of a bushing and adjusting the extending length of the pin sample, and the axial distance of the ceramic ball sample is adjusted by adjusting the distance between a support seat and the lower surface of a fixture head, so that the requirement of clamping ceramic ball samples with different diameters in a certain diameter range can be met. The fixture device is compact in structure, and has good applicability for the research of tribology behavior of materials in a rolling-sliding mixed state.

Description

technical field [0001] The invention belongs to the field of material friction, and in particular relates to a fixture device for rolling-sliding mixed friction test and a use method thereof. Background technique [0002] According to the research on the tribological behavior of materials by domestic and foreign scholars, the friction tests of materials are mostly sliding friction and rolling friction. , ball-disk pairing and ring-block matching pair, etc., and most of the matching pairs used to study the rolling tribological properties of materials are four-ball matching pairs, ring-ring matching pairs, and four-ball-rod matching pairs. [0003] For the rolling tribological behavior, it is usually impossible to be pure rolling, mostly rolling and sliding, and there are fewer types of matching pairs. In general, auxiliary test fixtures are required, and especially for ceramic materials, the molding process is more complicated. It is not easy to process into shapes such as r...
