Automatic Modeling System for Skeleton Model of Aircraft with Complex Surfaces

There are complex and repeated modeling works during the process of aircraft design, which leads to the heavy workload and low working efficiency. In order to improve the quality and efficiency of aircraft structure design, an automatic modeling system for skeleton model of aircraft with complex surfaces is developed based on CATIA VBA. The system can provide the generation of the main structure skeleton model of the aircraft, the creation/output of skeleton model properties and the automatic splitting of the aircraft skin. Besides, an aircraft design template is proposed to formalize the design standardization of aircraft structure and rapid modeling procedure. The efficiency and accuracy of the aircraft structure design are improved, and the finite element pre-processing time is shortened by the system.
