Description

technical field [0001] The invention belongs to the field of teaching aids, and in particular relates to a beam bending deformation simulation system based on engineering complex working conditions in the teaching of material mechanics. Background technique [0002] At present, under the background of new engineering, various majors are carrying out curriculum reform and teaching innovation. Through curriculum reform, students' learning methods and learning effects are constantly improved. For many engineering majors such as mechanical engineering, material engineering, and civil engineering, material mechanics is a very important professional basic course, and it is the basis for many subsequent professional courses. Rods are the research object of material mechanics. The rods with bending deformation as the main deformation are called beams. Bending is the most important part of the four basic deformations in material mechanics, and it is also the most important deformatio...

AI Technical Summary

Problems solved by technology

In the actual teaching of the existing material mechanics course, the learning of internal force and stress is mainly based on abstract hypothetical experiments, or through computer software picture analysis or animation demonstration, but such learning methods are not intuitive enough, and the learning effect of students needs to be further improved

At the same time, regarding the influence of actual conditions such as different loads, constraints, and beam dimensions on the beam's flexural strength and flexural stiffness in actual engineering, the existing classroom teaching usually calculates the bending moment and stress through theoretical derivation. The size of the method is carried out, and the students do not have the opportunity to conduct an intuitive comparison of the influence of the relevant influencing factors on the bending deformation, which does not use the understanding of the bending deformation of the beam
