Problems solved by technology

[0003] At present, most of the existing friction testing instruments are carried out on the rotating friction plate, which will cause the linear velocity of friction at different positions of the sample to be inconsistent, and the speed has a great influence on the wear condition.
And the current friction and wear measuring instruments cannot realize real-time information collection and analysis

Abstract

The invention provides a reciprocating type mechanical friction interface in-situ information acquisition device, and belongs to the technical field of mechanical friction detection. A reciprocating screw driving method is adopted, and the running speed is stable in the whole process. Since an experimental table is in a reciprocating mode, the speed of points of the friction of a sample to be measured is consistent; a method that a force sensor and acceleration sensor compensate each other is used, so that the precision of a friction force measurement result is very high; a pressure loading mechanism is controlled by a motor screw module, and the force sensor is used for real-time feedback. Before the experiment, the weight of a chuck on the lower part of the force sensor, the sample and the like is eliminated, so accurate loading is achieved. Different friction plates are replaced, so that the friction mechanical characteristics, wear conditions, the temperature and stress change of different sample bodies can be quickly and accurately monitored in real time and detected.

Description

technical field [0001] The invention belongs to the technical field of mechanical friction detection, and in particular relates to a reciprocating mechanical friction interface in-situ information acquisition device. 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 test instruments are carried out on the rotating friction plate, which will cause the linear velocity of...
