Research And Implementation Of AMDB-based Collaborative CAE System

Network-based collaborative simulation/analysis system (NCSS)is a new simulation/analysis pattern.In this collaborative system,A product development team can implement a collaborative simulation about products performance in a distributed network environment that computer hardware support.Network-based collaborative simulation/analysis system enhances the cooperation between enterprise and department, utilizes advantage of group work, improves the efficiency of product development,and enhances the competition ability of enterprise.Aiming at the situation and requirements of collaborative design of aviation enterprise,the paper based on the aviation material database (AMDB) deals with the theory and practice of key technologies in collaborative simulation/analysis system and the practice of cooperative tools integration including NetMeetingThe main research content are briefly summarized as follows:(1)The papeer analyzes the PCL language of MSC.PATRAN.The collaborative simulation/analysis system based on MSC.PATRAN are established.But the System has a shortage:the client and server can implement collaborative simulation in the same simulation environment but the client cannot get the simulation result from server. A WEB browse server is needed to solve this problem.(2) The material parameters are the key factor of the simulation/analysis system, so,Establishment of database of aviation material has a very important significance. Another, the database of aviation material is also the WEB system's operating targets.(3)ORACLE cannot provide the interface about MSC PATRAN PCL and MSC cannot provide the root language of PATRAN. So, what we can do is to find a intermediate tool to implement the interface of ORACLE and MSC PATRAN.XML suits this case.This paper use XML technology achieve the interface of ORACLE and MSC PATRAN and implement the standard interface of PCL and XML.(4) In the process of collaborative simulation/analysis system,the paper accept the technology of ORDBMS,J2EE,STRUTS,HIBERNATE,PCL and XML.(5) In order to enhance the application of the simulation/analysis system, the paper development a another system.The system introduces the B/S frame and J2EE technology and implement the browse function for the material database.In the program of the B/S system,the paper also research the improving the performance method.(6) At last,the paper validate the simulation/analysis system by the analysis of a unpiloted aerofoil.
