Using the structural parameterized modeling of fourbar combined arm-frame could achieve the modeling of FEA model under multi-ranges and full loading conditions.The generated model data file could be solved by calling directly the NX Nastran. The strength and fatigue analysis module of four-bar metallic structures picked up information of the corresponding node and unit in the f06file of NX Nastran result and carried out fatigue calculation analysis on the four-bar metallic structure recur to the decision-making of expert system. In the operation process the platform system carrying out data management of the model driving parameters and of the strength fatigue analysis result of structures with the aid of data base, and the data file generated simultaneously wag being classified and saved by the special purposed management module. The platform system has good compatibility,its data and file management system can be brought into the PDMS sub-system for carrying out effective management, thus provided favorable interface for further expansion of the system.
