Research On Simulation Of Multidisplinary Combination Properties About Aeronautic Case

With the development of CAD/CAE integrated modeling, the integrated Modular Electronic Equipment has become widely used more and more,and it is of great importance for improving overall performance of avionic devices to promote multi-disciplinary simulation analysis.wo must solidify the process to realize multi-disciplinary simulation analysis of Aeronautic Case,and make those software interfaces converged automatically in order to keep lossless conversion of datas.The platform will call related tools to complete the setup, simulation, display and a series of complex work in the background.Based on the CAD/CAE data integration,this paper used the secondary development of Pro/E and Icepak to finish multi-disciplinary simulation analysis in the C++ Builder 6.0 platform.We proposed feature classification extraction and components mesh extraction by use of the functions given by protoolkit.After a comparison,we chose the latter method to carry out triangular mesh by parts of the case,and compiled the information of nodes and surfaces into import files the CAE analysis follow-up needed.In order to avoid excessive interference caused by too many assembly features of the case model in the structure analysis,this paper proposed assembly feature transfer algorithm according to the elementree structure and the feature reconstruction ,and successfully transferred assembly features to the components related.To achieve that thermal analysis results could returned to the display interface automatically, by studying the Tcl language and the secondary development of Icepak,we compiled the Tcl commands into the executable files in the system to extract and display the temperature, pressure and other post-processing results automatically.Based on the principles and algorithms above-mentioned, multi-disciplinary simulation system achieved the structure and thermal coupled analysis about Aeronautic Case at last.
