Description

Technical field [0001] The invention relates to the field of research on the meso-mechanical behavior of materials, in particular to a multi-purpose meso-visual device with full-view three-dimensional adjustable. Background technique [0002] With the continuous deepening of research work in various engineering fields, the exploration of the mechanical behavior of the research object has entered the mesoscopic stage. For example, coal and surrounding rock materials in the field of mining engineering are no longer only satisfied with the study of their macroscopic dynamic phenomena and mechanical behaviors, and the initiation, development, penetration, brittle fracture, or mesoscopic micro-cracks after being stressed. The mechanism and influencing factors of the nucleation, growth and confluence of microvoids, ductile fracture, and macroscopic cracks and fracture failure are the current research hotspots. Another example is the study of the mechanical properties of materials such...

Problems solved by technology

At present, some scholars have developed related devices and equipment. Cao Shugang et al. invented a three-dimensional mobile microscopic observation device (application number: CN200820099769.3) using a hierarchical microscopic bracket arrangement mode. Its disadvantage is that the device is relatively complicated and cumbersome, and It is impossible to ensure that the observation line of sight and the crack development of the specimen are in a vertical perspective; Zhou Cuiying and others invented a three-axis adjustable microscopic observation system for rock soil softening mesomechanics test (application number: CN200910036622.9), which also has the disadvantage of being unable to Realize the vertical viewing angle observation of the crack development of different test pieces, and the size that cannot be adjusted accurately in three dimensions

In summary, most of the visual devices are used for a certain type of test, and there are deficiencies such as unreasonable overall structure design, simple structure but few observation functions, and many functions but complex and bulky devices.
