In this paper, a fighter radar aviation chassis as the research object , Pro / E, ANSYS, Icepak software for the F- fat objects , the choice of the appropriate development tools and database software , and the establishment of a fast- CAD modeling and CAE simulation analysis integrated expert system . The simulation expert system platform not only shorten the development cycle and improve design efficiency and design quality and success rate of development time . Thesis work are as follows : aviation chassis structure , based on the extract air chassis connector features as well as an important modeling parameters to use based on the analysis of characteristics of CAD / CAE integrated modeling approach , in order to achieve the CAD / CAE rapid integration of modeling ; then transferred to the CAE model WorkBench, in WorkBench under different model size , structure and key areas to determine the type of grid , the grid size and the principle of local refinement to achieve network grid automatically divided ; the library boundary conditions of the thermal , mechanical aspects integrated in the experimental platform , by the boundary conditions of load , thermal , mechanical simulation analysis , generate designer experiments customized report , and with the expected results comparison or evaluation of test results . A fighter radar unit as the research object , consider the versatility of the experimental platform , it is possible to achieve different structural forms of aviation chassis data validation ; lot of valuable experience in the data and experimental data for the simulation results of the experimental platform provide protection correctness ; experimental platform has good scalability , and related parts library, library materials , environmental conditions, library management, expand and update simple .
