Research on Multi-specialty Coordination, Multi-discipline and Multifunction Integration Oriented Modeling and Simulation Innovation Technology

The paper mainly covers the connotations, the functions and the key techniques of the Aircraft Digital Cooperative Robust Integration Optimization Performance Simulation Technology. The Performance Simulation Airplane Integration Design Platform, which has been established by the Performance Simulation Airplane construction analysis, a series of Standard Specification Establishing, the key modules development and a series of the supporting work implementation. It can be customized and be extended, and it is easy to be demonstrated. The platform contains the engineering database including the Performance Simulation Airplane model, simulation process data, simulation results data, and so on. It also provides the closed development process from the initial design to the optimized design, and end to the final detail design. It carries out the configuration selection and performance analysis for the airplane various configurations under the product development requirements in the entire process. It is applicable for the cooperative simulation analysis about the General Configuration research, the Aerodynamic design, the Structure design, the Strength design and some system specialties. This technique system has brought revolutionary changes to the traditional technological concept and Architecture, and it has been proved that the design period of the product is shortened by more than 25%, and the simulation test period is also shortened by more than 25%.
