Material mechanics deformation stress demonstration device with real-time image transmission function

Abstract

The invention discloses a material mechanics deformation stress demonstration device with a real-time image transmission function, belonging to the technical field of material testing and demonstration equipment. The device solves the problems that an existing demonstration device is relatively single in demonstration capability and relatively one-sided in function, and cannot well realize four-side extrusion deformation stress demonstration and central jacking deformation stress demonstration at the same time. The material mechanics deformation stress demonstration device with the real-time image transmission function comprises a synchronous frame and a connecting frame, wherein the whole demonstration box is of a square structure, the top end of the demonstration box is tightened and covered with a transparent cover plate, two transverse support positioning shafts are symmetrically supported on the bottom sections of the front and rear inner walls of the demonstration box, and two support frames are installed on the two transverse support positioning shafts in a sliding and sleeving mode; and the demonstration box is welded and fixed between the top end sections of two supportingleg frames. When four clamping plates slide in a gathered mode to extrude materials, the two supporting frames can be pushed to slide properly, so the front clamping plate and the rear clamping plateare prevented from being blocked, and normal implementation of mechanical deformation demonstration is guaranteed.

Description

technical field [0001] The invention relates to the technical field of material test demonstration equipment, in particular to a material mechanics deformation stress demonstration device equipped with real-time image transmission. Background technique [0002] Mechanics of materials is an important basic course for mechanical and civil engineering majors, and it is also a relatively abstract course, especially the content of the four basic deformation stresses of tension or compression, shearing, torsion and bending. It is difficult to truly understand with more vivid description and explanation methods. For example, for a simple bar shear deformation, students may understand the deformation characteristics of the shear deformation relatively easily, but they will feel a little powerless to let them really understand the shear stress distribution of the bar section. Therefore, in the teaching process of material mechanics, it is undoubtedly a good teaching method to use si...
