| Abstract: | In this paper,based on a semi-rigid structure of the stratospheric airship with an internal keel design,using ANSYS finite element analysis software,a computational model of the keel was established.By dealing with constraint condition and cell parameter,results of elements' stress and nodal displacement of the keel were obtained under gravity load condition.The simulation result comply with the specifications of structure design well,and a reference for semi-rigid structure of the stratospheric airship was... |
