Dynamic force chain observation device of flexible polishing wear particle group

Abstract

The invention provides a dynamic force chain observation device of a flexible polishing wear particle group. The dynamic force chain observation device comprises an image processing device and a particle control device. The image processing device comprises a light source generator, a light source collector and a data analyzer. The light source generator is located at the bottommost end of an observation region. The light source transmitted by the light source generator penetrates through a lower polarized light device and points to a particle control device in the observation region composed of the lower polarized light device and an upper polarized light device. The upper surface of the particle control device is covered with a transparent baffle. The light source collector is located over the upper polarized light device. The light source collection view of the light source collector covers the light source transmitted out by the upper polarized light device. The data input end of the data analyzer is connected with the data output end of the light source collector. The data signal output end of the data analyzer is connected with a display screen of the data analyzer. The dynamic force chain observation device has the advantages that the external applying parameters of photoelastic particles can be detected in real time, the motion state of the photoelastic particles can be adjusted through sliding blocks, and simulation of the flexible polishing machining test is achieved.

Description

technical field [0001] The invention relates to a flexible polishing abrasive particle group dynamic force chain observation device. Background technique [0002] In the process of flexible polishing ultra-precision machining, the particle system composed of a large number of abrasive particles improves the surface quality of the workpiece under the support of flexible processing tools, so that the surface of the workpiece is smoother and has a longer service life in industrial applications. However, in the flexible polishing method, due to the flexible feature of the support tool, the abrasive particle system is in a consistent state of motion with the processing tool macroscopically during the processing process, but the abrasive particle system is extruded with each other on the microscopic level to form fretting, and its particles The micro-mechanical state between them also changes accordingly. The ultra-precision machining method of flexible polishing requires the imp...
