Comprehensive experiment platform for material mechanics

Abstract

A comprehensive experimental platform for comprises a bottom plate, T-shaped grooves are formed in the upper side face of the bottom plate, and the two T-shaped grooves are of a central symmetry structure with the center of the bottom plate as the center. The invention further provides a force loader, a deflection testing device and an inclination angle testing device, the force loader can walk in the T-shaped groove, a contact head is arranged at the top end of the displacement sensor, and the contact head makes contact with the bottom face of the deflection testing sample and applies deflection testing acting force to the deflection testing sample. The inclination angle testing device is used for clamping a deflection testing sample, and inclination angle data of the deflection testing sample are obtained through an inclination angle sensor. According to the invention, the symmetrical base structure can accommodate a plurality of students to carry out two different electrical logging experiments; the inclination angle testing device is arranged, deflection rotation angles are visually measured through a sensor, the deflection rotation angles of the sample can be measured at any point, and the experiment testing efficiency is improved. The invention relates to an experimental device capable of carrying out a plurality of material mechanics experiments.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, more particularly, to a comprehensive experimental platform for mechanics of materials. Background technique [0002] Mechanics of materials is an important professional basic course in many science and engineering colleges. Some of the concepts have abstract meanings, which make students unable to truly understand them. Therefore, most schools offer experimental courses to deepen students' understanding of the concepts of mechanics of materials. However, most of the existing experimental instruments are designed separately for different experiments in material mechanics experiments, which makes it impossible for students to complete multiple types of experiments on the same instrument, which affects the experimental efficiency. In addition, too many experimental instruments occupy a lot of teaching laboratory space, which increases the cost of teaching experiments. [0003] In a smal...

AI Technical Summary

Problems solved by technology

[0006] 1. The function is single, and it can only test stress, strain or torque, etc., which takes up more laboratory space and increases teaching costs;

[0007] 2. The stress loading of the whole specimen cannot be realized, and the load can only be increased at the fixed position of the specimen;

[0008] 3. The transmission mechanism used by some experimental instruments is worm gear transmission. This transmission structure will cause problems such as bulky experimental instruments and large space occupation.
