  The present invention relates to an analysis procedure extraction apparatus and an analysis procedure extraction method for extracting an analysis procedure when an analysis is performed using a computer and analysis software.

  In order to enhance product competitiveness, efforts are being made in the manufacturing industry to apply CAE (Computer Aided Engineering) analysis from the product design stage to shorten the product development period and reduce development costs. In general, in CAE analysis, a series of procedures such as creation of a shape model to be analyzed, creation of an analysis mesh, setting of analysis conditions, execution of analysis, and the like are performed by executing analysis software. These procedures differ depending on the product to be analyzed and the phenomenon evaluated by the analysis, and analysis beginners often acquire analysis techniques while gaining experience, such as learning know-how from analysis experts. Therefore, analysis beginners sometimes do not have sufficient knowledge and know-how about analysis. Knowledge and know-how about analysis differ depending on the target product and the physical phenomenon to be requested. Furthermore, if the product is the same but the usage environment is different, analysis know-how corresponding to each usage environment may be required. is there. For this reason, a delay occurs in the design, such as occurrence of rework in the analysis, and repetition of trial production and experiment without performing the analysis.

  To solve such inconvenience, it is effective to provide various analysis know-how to analysis beginners. As a conventional technique related to analysis support for analysis beginners, an analysis navigation system that visualizes analysis convergence determination know-how is known (see, for example, Patent Document 1). In addition, a method for providing an analysis process according to the purpose of analysis and constraint conditions is known (for example, see Patent Document 2).

Analytical know-how such as boundary conditions and material constants set in the analysis is not included and must be studied by the designer.

  In addition, the system disclosed in Patent Document 2 discloses a system that displays what preprocessor, solver, and postprocessor should be used based on the content of analysis as the purpose of analysis and the calculation time and type of computer as a constraint. However, it does not provide know-how for setting conditions in analysis, such as analysis know-how specific to the analysis target.

The analysis procedure extraction system 1 includes an analysis procedure reading unit 3, an analysis procedure decomposition unit 4, an analysis procedure calculation unit 5, an analysis procedure extraction unit 6, and an analysis procedure extraction result display unit 7.

  In the analysis procedure storage unit 2, the analysis procedures performed so far are divided and structured for each main analysis item. The analysis procedure reading unit 3 reads the analysis procedure stored in the analysis procedure storage unit 2 into the analysis procedure extraction system 1. The analysis procedure decomposition unit 4 decomposes the analysis procedure read by the analysis procedure reading unit 3 into analysis main items such as material setting and constraint condition setting. The analysis procedure calculation unit 5 compares keywords assigned to main items of the analysis procedure decomposed by the analysis procedure decomposition unit 4.

The analysis procedure extraction result display unit 7 displays the analysis procedure extracted by the analysis procedure extraction unit 6 on the input / output device 8 and shows it to the user.

Next, processing contents in the analysis procedure extraction device according to the present embodiment will be described with reference to FIGS.
First, an example of the data structure of the analysis procedure registered in the analysis procedure storage unit 2 of the analysis procedure extraction device according to the present embodiment will be described with reference to FIGS.
2 and 3 are explanatory diagrams illustrating examples of data structures of analysis procedures registered in the analysis procedure storage unit of the analysis procedure extraction device according to the embodiment of the present invention.

  FIG. 2 shows an example of the analysis procedure registered in the analysis procedure storage unit 2 shown in FIG. The analysis procedure is registered for each analysis example. Here, an analysis procedure named “stress analysis analysis procedure data 001” is shown as an analysis procedure related to the stress analysis of the vehicle.

  The analysis procedure is registered in WBS (Work Breakdown Structure) format, and the analysis procedure name, the analysis target, and the use area of the analysis target product are displayed in the analysis name display section 9 as, for example, “stress analysis / vehicle / Japan”. The

  A material setting 10A, a constraint condition setting 10B, a load setting 10C, a deformation amount setting 10D, a mesh creation 10E, an analysis execution 10F, and a result evaluation 10G, which are analysis main items 10, are set as the first hierarchy of the WBS.

  In the second hierarchy, a procedure is stored as an analysis procedure 11 for each main item. Each analysis procedure has a structure given an operation name / keyword. For example, the material setting 10A, which is the main analysis item 10, stores the material / temperature dependency 11A and the analysis procedure of the material setting / composite material 11B. Here, it is assumed that two analysis procedures are stored in one analysis main item 10, but in reality, 10 to 20 analysis procedures are generally stored. For convenience, only two are illustrated. Further, the constraint condition 10B, which is the main analysis item 10, stores the analysis procedure of constraint condition setting / displacement constraint 11C. Although the analysis procedure is registered in the WBS format here, it may be used as long as the analysis main item and the analysis procedure can be expressed in a flowchart or the like.

  FIG. 3 shows an analysis procedure for the material setting / temperature dependency 11A among the analysis procedures shown in FIG. By clicking the operation name and keyword display shown in the second hierarchy of FIG. 2, the analysis procedure screen of FIG. 3 is displayed.

  In the analysis procedure, an operation method name 11A1, a keyword 11A2 shown in the second hierarchy in FIG. 2, and a specific operation method 11A3 are registered.

  As a specific operation method 11A3, in the illustrated example, the operation method “set temperature dependence on material properties” is displayed. In this example, for example, when “Material” is selected from the “Menu” column 11A4, the “Material” column 11A5 is displayed in the right column. For example, the Young's modulus can be entered in the Young's modulus input field 11A6. In this example, since temperature dependency is set, when “temperature” on the right side of the input column 11A6 is selected, the “temperature dependency of Young's modulus” column 11A7 is displayed, and the temperature input column 11A8 and Young's modulus are displayed. By inputting the Young's modulus at each temperature using the input column 11A9, the temperature dependence of the Young's modulus can be set.

  As described above, the operation method is specifically visualized while using the screen display of the analysis software, so that even a beginner with little analysis experience can proceed with the analysis work.

In addition, it specifies which of the analysis common procedure and analysis know-how regarding the input product name and product usage region is to be extracted. When there are few analysis procedures registered in the analysis procedure storage unit 2, it is possible to extract analysis common procedures and analysis know-how for all registered analysis procedures. However, if there are a large number of registered analysis procedures, the analysis procedures that meet the user's analysis objectives can be extracted in a short time by narrowing down the analysis common procedures and the analysis procedures to extract the analysis know-how. It becomes possible to do.

  FIG. 5 shows an input example of the analysis procedure extraction word. In this example, “stress analysis” is input to the analysis type input unit 13, “vehicle” is input to the product name input unit 14, “Hokkaido” is input to the product use region input unit 15, and the know-how instruction unit 16 in the product use region is checked.
