    Abstract
  • In order to improve the quality and efficiency of civil airplanes conceptual and preliminary design, the method of wing structural finite element modeling and automated adjustment in a computer aided aircraft conceptual/preliminary design system called open conceptual aircraft design system(OpenCADS) which organizes data in an object-oriented approach was studied. The equivalent method of wing structural finite element modeling using beam elements and shell elements in conceptual design was proposed. The finite element nodes which were calibrated by ribs and number rule of the elements were defined. The organization and application logic of related data classes was designed and wing structural finite element modeling and automated adjustment were implemented which laid the foundation for multi-disciplinary design optimization in aircraft conceptual design phase. An example was presented to illustrate the effectiveness and reliability of the method proposed.
