Description

Intelligent interaction operation method and system for rod system structure displacement method calculation
Technical Field
The invention relates to the technical field of intelligent teaching, in particular to an intelligent interaction operation method and system for calculating a rod system structure displacement method, which are applied to the fields of mechanics of construction, engineering mechanics, construction mechanics and other mechanics teaching in higher education.
Background
The displacement method is a calculation and analysis method for internal force and deformation of a rod system structure. The displacement method uses node displacement as basic unknown quantity, and utilizes the principle of linear elastic superposition to establish equation calculation according to the balance condition of the basic structure (or basic unit) of the displacement method at the node (or rod end) displacement. The displacement method is the most commonly used calculation method in engineering analysis, and most practical numerical calculation and conceptual analysis of engineering are performed based on the displacement method. Through the learning of the displacement method, besides the structural response is obtained, the basic rigidity characteristics of the structure can be sensed and mastered in the calculation process, and the method has strong teaching and engineering practical significance for understanding the basic mechanical properties of the structure and mastering the corresponding mechanical concepts.
The displacement method is a comprehensive calculation method, and the operation process integrates the processes of counter force, internal force and deformation (displacement) calculation, internal force graph drawing, displacement method basic structure, basic system selection and the like. According to the basic concept of the displacement method, the number of unknowns may also change if the unit form is not limited; at the same time, there is the possibility of variation in unknown quantity properties and positions due to the presence of infinite rigid cross-sectional features (engineering settings often found in manual displacement method topics, including infinite flexural stiffness, or infinite axial stiffness). Therefore, the displacement method calculates the number and the property of unknown quantities, which may still vary from person to person in the calculation process, and the calculation process is not necessarily unique.
The traditional paper operation mode has the defects of staggered pictures, texts, formulas and symbols, multiple steps, high manual reading strength and difficult realization of automatic reading; meanwhile, the manual reading mode is long in period and cannot be fed back in time.
With the development of computer, internet and other technologies, traditional teaching, online teaching, hybrid teaching and other teaching modes provide higher requirements for teaching interaction technology, but other teaching assistance and structure analysis software at home and abroad at present have no complete man-machine interaction operation function of a displacement method.

1. the user clicks an interactive operation control button in a third interactive operation area of the interface, calculates an interactive operation option by a displacement method in a pull-down menu, clicks the option, automatically pops up a question bank, then selects a question in the question bank by the user, loads and displays the selected question in a process graphic display area in the man-machine interactive interface after the user selects the question, automatically pre-analyzes the selected question, analyzes a possible displacement method degree-of-freedom value range corresponding to an original rod system structure of the question, stores the value range, and compares and judges errors of n based on the value range after the user inputs the displacement method degree-of-freedom value n. The user clicks the "displacement method calculation" key of the second interactive operation area, the lower left corner of the window where the second interactive operation area is located prompts the user to input the displacement method degree of freedom value n in the process of calculating the displacement method judged by the user, as shown in fig. 3, the user can input the displacement method degree of freedom value by selecting a mode, after inputting the displacement method degree of freedom value n, the process graphic display area in the interface is divided into n+4 graphic display windows, as shown in fig. 4, at the moment, the stem of the subject (namely, the text part above the graphic in the first graphic display window in the diagram is "calculate the graphic structure by the displacement method" and draw the bending moment diagram ") and the original bar system structure (namely, the calculation model in the diagram) are displayed in the first graphic display window, and the rest graphic display windows are reserved windows. For this example, the correct degree of freedom of displacement method n=1, after input, it is determined that the system automatically generates and adds menu items (i.e., the drop-down menu of the "displacement method calculation" button in the second interaction region, including forming a basic structure (displacement method basic structure drawing control), m_1 (1 st state unit moment diagram drawing control), m_p (load moment diagram drawing control), M (result moment diagram drawing control)).
2. And then the user interactively draws each graph corresponding to the original bar system structure in the title in the first interactive operation area and the second interactive operation area. As shown in FIG. 4, the user clicks the "form basic structure" button in the second interactive operation region, and may add "user-defined" additional constraint in the original bar system structure by adopting different modes such as additional horizontal bar, vertical bar or rotation constraint in the first interactive operation region, after the operation is completed, the graph of the corresponding basic structure of the displacement method is loaded and displayed in the second graph display window by double clicking the generated basic structure of the displacement method, the user clicks M_1 and M_ P, M respectively, applies corresponding unit force on the submitted basic structure of the displacement method, draws the corresponding internal force graph and submits the graph, the user calculates according to the displacement method and draws the final internal force graph, and the calculation of the displacement method is completed. The process graphic area is shown in fig. 5, wherein the basic structure of the displacement method is obtained by adding additional constraint to the basic structure of the original rod system in the subject, the M_1 bending moment diagram is the 1 st state unit bending moment diagram, the M_P bending moment diagram is the load bending moment diagram, and the M diagram is the resultant bending moment diagram.
3. After the displacement method interactive calculation is completed, the result is submitted, the system is submitted to read, and the read result is displayed in a process graphic display area of the human-computer interaction interface in a floating window mode in real time according to the currently set read mode, as shown in fig. 5, and of course, the read result can be uploaded to a server for storage. The explanation result is shown in fig. 6 specifically, and includes the accuracy judgment of key operation steps (such as the input degree of freedom of the displacement method, and the graphs of the basic structure, the unit bending moment diagram, the load bending moment diagram, the result bending moment diagram and the like which are drawn interactively) corresponding to each knowledge point and the corresponding total score of the question.
If the user uses different calculation ideas, for example, the input degrees of freedom of the displacement method are different, the solution changes correspondingly, and the calculation process also changes correspondingly, so that the obtained basic structure, unit bending moment diagram and load bending moment diagram of the displacement method can change correspondingly, but if the solution process is correct, the final result bending moment diagram can be the same. The user uses a solution method different from the solution method shown in fig. 5, the degree of freedom value of the displacement method input at this time is 2, so that two unit bending moment diagrams in different states, namely an M_1 bending moment diagram and an M_2 bending moment diagram in fig. 7, are correspondingly and interactively drawn, and the final result bending moment diagram is consistent with the result bending moment diagram obtained by the method shown in fig. 5 due to the correct calculation process. If an error occurs in the calculation process of the user, the graphic display area of the process and the reading result are shown in fig. 8.
According to the technical scheme, the operation process is performed according to the basic step sequence of the displacement method analysis, and the operation can be performed and submitted only by meeting the self-consistency of the process; the operation degree of freedom is extremely high, and the operation process on paper is completely reduced; in the analysis, drawing and other calculation processes, except the basic fixed steps according to a displacement method, the method does not need to give an induction prompt, and the learning level of students is evaluated, checked and examined objectively; meanwhile, accuracy judgment can be provided for each operation step in real time, and training efficiency of beginners is ensured.
The basic process of calculating the man-machine intelligent interaction for the clearer expression displacement method is shown in a flow chart 9 corresponding to the operation steps. It can be seen from the figure that, except for the number range of the unknown quantity (namely, the range of the degree of freedom of the displacement method) and the judgment of the final internal force solution, the judgment of the rest states is directly from the original rod system structure (the basic property of the structure is completely irrelevant to the calculation process of the displacement method), and the judgment of the rest states is required to be carried out based on the actual operation of the user in the calculation of the displacement method (different analysis ideas and different operations are needed).
The image-text interaction mode is convenient, so that a user can conveniently input graphics and data, and the working repeatability can be avoided and the working time can be shortened under the condition of not reducing the calculation analysis amount; meanwhile, the judgment of the operation steps is based on the basic concept of the displacement method, the problem of absolute universality of the displacement method is solved, the problem of multiple solutions is solved basically, any load, constraint or structural characteristic can be used for analysis and calculation on the system platform as long as the system is any rod system structure suitable for analysis of the displacement method, the system can adapt to the solving process and make accurate review, and the system can also accurately judge and position errors. When the examination is not examined, according to the errors pointed by the reading, only the error operation is carried out, and the drawing and the correction are carried out again without the repeated questions. The invention can be used for working exercise in the learning stage and also can be used for examination or examination. Can provide beneficial assistance for various on-line and off-line teaching modes.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
