The system comprises a PDMS output module, a load and parameter setting module, an MIDAS input module and a modified-information feedback module, wherein the PDMS output module judges the information of a model bar according to the attributes set by a three-dimensional solid model, and sends the generated text file of the model bar to the load and parameter setting module; the load and parameter setting module sets the load and design parameters of the model bar according to the text file so as to form a text file which has a load composition and is used for analyzing and calculating building structures, and sends the formed text file to the MIDAS input module; the MIDAS input module receives the text file which has a load composition and is used for analyzing and calculating building structures, imports the text file into the MIDAS software, and transmits the calculated result file to the modified-information feedback module; the modified-information feedback module receives the calculated result file, performs comparison and automatically modifies the bar. According to the system disclosed by the present invention, a conventional process that a calculation diagram is simplified through a structural concept is omitted; on the aspect of data transmission, the data can be simultaneously transmitted to related specialties, so that the inconvenience during cooperation of paper files is avoided, and the establishment of a model is faster and more accurate.
Description
Technical field
The present invention relates to a kind of method of carrying out application development on PDMS basis of software, mainly realize PDMS software and export the conversion of data to MIDAS software input data.Three-dimensional entity model relevant in PDMS software directly can be imported in MIDAS software by application personnel, thus improve three-dimensional structure modeling efficiency.
Background technology
PDMS(Plant Design Management system) namely factory's three dimensional arrangement design management system as a kind of three-dimensional design management software be widely used in power plant engineering design in, also give building structure specialty provide good modeling environment.At present, more common Architectural Structure Design
finite element analysis softwaremIDAS(Multi-tier Distributed Applications Services) analytical calculation can be carried out to building structure, for current building field brings guaranteed reliability.
Composition graphs 1, Fig. 1 is traditional utilize MIDAS calculation and analysis methods.Designer sets up building structure three-dimensional model in PDMS software, generate two-dimentional drawing, paper counterparts is utilized to be distributed to computing staff, computing staff becomes calculation diagram by structuring concept simplified design model, and simplified model is set up in MIDAS software, then by the method for artificial programming, additional load is input in MIDAS software in MIDAS software, thus calculate the reliability of building structure, after result of calculation to be obtained, data feedback will be calculated to designer, as fruit structure is reliable, then need not revise, as fruit structure is unreliable, so designer needs to revise model in PDMS, so repeatedly, till treating that structure is reliable.There is following shortcoming in said method:
One, because designer and computing staff are with paper document transmission, and designer sets up three-dimensional model in PDMS, and building structure is once upgrade, and paper document just must upgrade again, thus increases the weight of designer's workload;
Two, personnel to be calculated obtain paper document, need re-establish model, task is repeated in MIDAS software.
Three, existing PDMS software is mainly used in the foundation of three-dimensional model, and the file externally exported only with the attribute of model, and can not arrange the features such as pattern checking, load, rod member degree of freedom and rod member numbering, can not export the file with above-mentioned feature;
Four, existing MIDAS software is before computational analysis, need in this software Modling model, the model that PDMS software is set up can not be applied in this software, and in MIDAS software, arrange the dispersion of the information interface such as load, operating mode, load combinations needs artificial input, increases error rate, and result of calculation can not feed back in PDMS software, increase the error rate of amendment.
Summary of the invention
The present invention solves existing method cannot realize directly importing from PDMS software to MIDAS software the problem of data, provides the data transformations system a kind of to realize by PDMS software to MIDAS software.
Realize by the data transformations system PDMS software to MIDAS software, this system comprises PDMS output module, load and parameter setting module, MIDAS load module and amendment information feedback module;
The attribute of PDMS software to three-dimensional entity model is utilized to arrange, described PDMS output module is according to the information of the determined property model rod member arranged, by the node of reading model rod member, cross section and the text of coded message generation model rod member arranging model rod member, and described text is sent to load and parameter setting module;
The text of the model rod member that described load and parameter setting module export according to PDMS output module, by man-machine interactive interface, model rod member load and design parameter are set, concentrate and dose working condition and Load Combination parameter, automatically Load Combination is carried out, formed and there is Load Combination and the text calculated for structural analysis, and be sent to MIDAS load module;
What described MIDAS load module reception load and parameter setting module sent has Load Combination and the text calculated for structural analysis, and import in MIDAS software, MIDAS software is adopted to calculate model rod member, and form result of calculation file, and destination file is sent to amendment information feedback module;
Described amendment information feedback module receives result of calculation file, the text of model rod member result of calculation file and PDMS output module generated compares, whether identical according to the cross section of the node comparison model rod member of model rod member, find out the rod member that will revise, and highlighted display in 3-D view, designer to be interrogated revises rod member after whether revising automatically.
Method for transformation is as follows:
1, three-dimensional model set up by PDMS software, merges, change connected mode the node of the beam of this model, post, support, plate stem part, and checks bar cross section whether all in cross-sections match table; The actual building of simulation adds load at its stress point, and input load value size; The degree of freedom of rod member is discharged, can relative motion; By all rod members with rod member attribute for according to judging rod member type, give numbering, and export design document by PDMS output module;
2, load and parameter setting module are according to the fileinfo received, and concentrate and dose working condition and Load Combination parameter; Export the design document with Load Combination parameter and working condition; The file of output is directly imported in MIDAS software; Model is calculated; Generate result of calculation; Result of calculation is imported in information feedback module, and compares with source document, find out the rod member that will revise; Amendment rod member, and pass amended rod member information back PDMS output module.
Beneficial effect of the present invention: data transformations system of the present invention can depart from traditional process being simplified calculation diagram by structuring concept, the substitute is the three-dimensional entity model in PDMS Three-dimensional Design Software.In data transmission, relevant speciality can be distributed to simultaneously, eliminate all inconvenience that handy file made of paper coordinates, make the foundation of model more quick, accurate.On the basis of the data file of PDMS software derivation, designer directly, efficiently can also add load information by the setting option of human-computer interaction interface, obtain the design document for Architectural Structure Design, directly apply to MIDAS software and carry out analytical calculation, and result of calculation and amendment information are returned in PDMS, automatically revises model.
