Modeling And Simulation Of Deformation And Performance Coupling Of Airborne Microstrip Antenna Array Based On SysML

Model-based systems engineering can control the product design process from the point of view of the system,and SysML can implement the corresponding model.Multidisciplinary analysis and design can provide a feasible scheme for the analysis of complex products.With the development of its function and structure,the microminiaturization and portability of airborne antenna have become the necessary development trend.But in the actual working environment,the electrical performance of the antenna will change with the deformation of the carrier and the change of the antenna itself,and the deformation and the performance will affect each other.Based on this,this paper completes the following work:1.An improved V-map model based on model for systems engineering is proposed.The classical V model is mapped by layers,the V-map model in this paper is proposed,and the V-map model is described by layers,so that the whole design life cycle of the product can be managed by layers.The architecture of the V-map model is realized by using SysML to take the airborne antenna array as the object.It adds a new modeling idea to the classical MBSE theory.2.The design process of electronic equipment was analyzed and modeled based on SysML,and the SysML modeling results of airborne microstrip antenna array were obtained.According to the SysML modeling results,the physical modeling analysis of the microstrip antenna unit,wing structure and airborne microstrip antenna array was carried out,and the deformation and performance coupling model of airborne microstrip antenna array was obtained.The position information of the finite element model is extracted to reconstruct the deformation of the wing,which provides the shape and position information for the analysis of the electrical performance of the wing antenna after deformation,which is conducive to the monitoring of the change of the electrical performance of the antenna,and provides a way of thinking for the deformation and performance control of the airborne microstrip antenna array in the actual working environment.3.The classic V model is mapped to the layer analysis,obtained through the model transfer management model,the multidisciplinary analysis of V SysML based on the multidisciplinary analysis of airborne microstrip antenna array model is modeled,and from the three subsystems of airborne antenna array parameter analysis,for more complex physical device of a multidisciplinary analysis and simulation provides a train of thought.Through the above work,the V-MAP model based on MBSE theory is obtained,and the airborne microstrip antenna array is taken as the object to implement the V-MAP model based on SysML.The physical modeling of airborne microstrip antenna array is carried out,and the deformation and performance coupling model of airborne microstrip antenna array is obtained.Furthermore,the analysis layer V model based on MBSE theory is obtained,and the multidisciplinary parameters of the airborne microstrip antenna array are analyzed.This paper provides an idea for the whole product design and analysis life cycle of airborne microstrip antenna arrays and similar products.
