    Abstract
  • A new method for modeling the composite structure of high altitude delivery carrier through the way of ‘subsection meshing and joint binding’ is proposed, and a corresponding model is constructed by means of the finite element analysis software Abaqus. Then, the modal analysis on the composite structure is conducted in the case of free boundary condition, and the natural frequencies and mode of vibration of first 30 orders are obtained, respectively. The results show the individual vibration magnitude distribution of different composite structure part and the weak areas for vibration, and reveal the characteristics of vibration modals in different natural frequencies, which may provide a reference for structural improvement and optimization design of the delivery carrier
