Description

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

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
