Abstract

The invention discloses a rotary mechanical friction interface in-situ information acquisition device, and belongs to the technical field of mechanical friction detection. The rotary mechanical friction interface in-situ information acquisition device adopts gear drive and is stable in whole operation speed; and a torque sensor is used for detecting the torque change in the whole experiment process, an encoder is used for detecting the angular acceleration of a friction mechanism, the influence of inertia force is eliminated through a calibration result prior to the experiment, the precision of the measurement result of the friction force is very high, and the rotating speed of the friction mechanism can be accurately regulated and controlled. A loading and monitoring mechanism performs real-time feedback on a force sensor, the weight of a chuck, a sample and the like below the force sensor is eliminated prior to an experiment, the influence of gravity on loading is eliminated, and accurate loading is achieved; and moreover, different friction plates can be replaced to quickly and accurately monitor and detect friction mechanical properties, wear conditions and the like of different samples in real time.

Description

technical field [0001] The invention belongs to the field of mechanical friction detection, in particular to a device for acquiring in-situ information of a rotating mechanical friction interface. Background technique [0002] Tribology is the science that studies the interaction between surfaces during the relative motion of objects. It is an interdisciplinary subject involving fields such as mechanics, physics and chemistry. The changes in surface topography, surface composition, and structure induced by friction are very complex. Due to the diversity of surface properties, material types, lubrication states, and environmental atmosphere effects, the friction interface changes rapidly with time during the experiment. Therefore, real-time in-situ analysis of the friction contact surface is required. [0003] At present, most of the existing friction testing instruments observe and detect the sample after the friction experiment of the sample is finished, and cannot detect...
