Mechanics intelligent analysis system based on human-computer interaction

Abstract

The invention discloses a mechanics intelligent analysis system based on human-computer interaction. The mechanics intelligent analysis system based on the human-computer interaction includes a question generation module, a function selection module, and a result output module; the question generation module automatically generates test questions and corresponding mechanical models by inputting data files; the function selection module determines whether to perform analysis based on a static force or perform analysis based on a dynamic force according to the mechanical model of each test question; if the analysis is based on the static force, the function selection module includes a counter-force calculation module, an axial force calculation module, a shear force calculation module, a bending moment calculation module, and a deformation calculation module; if the analysis is based on the dynamic force, the function selection module includes a dynamic analysis module, a vibration modedisplay module, and a dynamic display module; and the result output module is configured to output a corresponding mechanical analysis result according to the function selected by the user in the function selection module. The effects of the mechanics intelligent analysis system based on the human-computer interaction are as follows: the data format is simple, the input is convenient, the operation is easy, the mapping accuracy is high, and the real-time and dynamic natures of online teaching interaction can be realized. An intelligent automatic parameter changing function is provided, which can be conveniently used for the construction of a question bank.

Description

Technical field [0001] The invention relates to intelligent teaching technology, in particular to a mechanics intelligent analysis system based on human-computer interaction in the teaching fields of "structural mechanics" and "engineering mechanics". Background technique [0002] At present, online teaching and network teaching models are in a stage of rapid development. Among them, in the teaching of engineering mechanics courses, the expression of computational diagrams has become a bottleneck technology in online teaching. The main problem is that the teaching process and calculation exercises require a lot of graphics. Expression, but the parameters of hand-drawn graphics are complex and require a certain degree of accuracy. In the interaction of teaching and learning, graphics are difficult to describe directly through text. Therefore, the more concise expression of the calculation diagram in the computer system and a more effective way of interaction between users are the ...

AI Technical Summary

Problems solved by technology

[0003] The existing general-purpose and mature business analysis software is mainly applied in engineering analysis, and the intuitive expression of the characteristics of teaching models and engineering models is insufficient. The specific drawing effect still cannot meet the needs of calculation models and graphics used in teaching.

[0004] In terms of question bank construction, the current mechanics question bank is still built for each question, which results in a large workload for question bank construction, and it is difficult to avoid duplication of questions in a short period of time

However, the construction of the practice question bank that requires a large amount of questions to achieve the purpose of mechanics training is basically not feasible in this way. Therefore, the current practice homework can only rely on the exercises attached to the teaching materials and limited teaching materials, which results in a small number of questions. Slow updates for good training purposes
