An Airborne Electronic Equipment Multidisciplinary Design Optimization Application

The airborne electronics is the key apparatus in launching, flight control, aircraft navigation, target acquisition in the entire flight process, whose reliability affects the current aircraft overall performance and the security.This paper studied the airborne electronic multi-disciplinary optimization design decomposition and the coordinated strategy, established the airborne electronics multi-disciplinary optimization design method, connected the realization designs and optimizes analysis, speeded up the design process. The multi-disciplinary model expression method of airborne electronic was studied in entire process, entire factors systematic and entire performance and analyzed its composition. The electronic product multi-disciplinary model composition, the design object tree's production, design parameters and function was optimized, and the frame of complete electronic product multi-disciplinary model establishment method was shaped. This paper summarized the engineering approximation algorithm of multi-disciplinary optimization, which constituted a complete multi-disciplinary design optimization algorithm structure and played a vital role in the optimization process. After analyzing the vibration and thermal disciplinary, the key parameters which affected the single disciplinary was obtained, which had carried on the iSIGHT multi-disciplinary optimized analysis, the component layout optimized size was obtained, enhanced the overall performance. And then the electronic approximate model production method was introduced, and influence tendency between key parameters and single disciplinary was obtained. At last the response surface model was established to express the module approximate model, which built the foundation for the following complete machine level multi-disciplinary optimized design.
