Abstract

Disclosed is a rolling, sliding and twisting experimental device. The device comprises an experimental table, an upper experimental piece and a lower experimental piece; the upper experimental piece and the lower experimental piece which are matched up and down are placed and installed on the experimental table, the experimental table is provided with a rolling sliding device and a twisting device, the rolling sliding device is horizontally installed above the experimental table and fixedly connected with the upper experimental piece, the twisting device is vertically installed under the experimental table and connected with the lower experimental piece, and the contact surface of the upper experimental piece and the lower experimental piece is further provided with a pressure sensor. Thedevice can simulate various movement forms such as rolling, sliding, rolling sliding, twisting and rolling-sliding-twisting compound movement and is simple in structure, easy to operate, stable duringrunning, adjustable in movement mode, accurate in test and long in service life.

Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a rolling-sliding torsion experimental device capable of measuring contact mechanical characteristics and friction and wear characteristics of contact materials during rolling, sliding, rolling, torsion and rolling-sliding torsional combined motion. Background technique [0002] Rolling torsion devices mainly exist in structures that use rolling as the main form of motion, such as vehicle tires, pulleys, and human lower limb joints. The experiment of the rolling-sliding torsion device can simulate rolling, sliding, rolling, torsion and rolling-sliding torsion, etc., to determine the mechanical properties of the contact material and the geometric dimensions of the prosthesis. Therefore, experimental equipment that can realize the rolling-sliding-torsional compound motion characteristics is very important to verify the mechanical properties and shape design of materials.

AI Technical Summary

Problems solved by technology

[0003] Most of the current experimental devices are single sliding, rolling or simple torsion, and the number of experimental machines that comprehensively consider various motion forms is not large, resulting in the incompleteness of experimental data, which will have a certain impact on subsequent design links At the same time, the repeated purchase of the machine will also cause a waste of funds and experimental space
