    Abstract
  • Aiming at the design and analysis of stratospheric airship rigid and flexible integrated large complex structure system, this paper carried out the simulation analysis of dynamic characteristics of airship envelope material with concentrated mass. The structural parts with high stiffness and relatively concentrated mass are simplified as concentrated mass. The airship envelope is simplified as a biaxially stretched cross envelope material sample. Firstly, the influences of the number of open arm slits on the stress transfer uniformity in the central region of the cross envelop material sample are analyzed. Then the influences of pretension, mass and concentrated mass of the size on the natural frequency of cross film material sample are analyzed. The influence of the mass and concentrated mass of the size on the natural frequency of the airship capsule is also reflected. The results show that the uniformity of stress transfer in the central region of the cross envelop material sample is better with the increase of the number of arm slits. When the number of arm slits is 3, the proportional coefficient of stress transfer uniformity is 0.943. In addition, the natural frequency of the sample increases with the pretension increase, decreases with the mass of the concentrated mass increase, and increases with the side length of the connection between the concentrated mass and the sample increase. The fundamental frequency of the sample is independent of the height of the concentrated mass, but the second and third order frequencies decrease with the height of the concentrated mass increase. The second and third order frequencies are significantly more affected by various physical quantities than the first order. Under the condition of the same pretension and mass, the influence of the height of the concentrated mass on the second and third order frequencies of the cross envelop sample is higher than that of the side length. The research results provide a theoretical basis for the overall design and analysis of airship structure and the further dynamic experiments of airship envelope materials with concentrated mass.
