| Abstract: | An airdrop cabin is useful cushion equipment to solve the problem of safe landing of airdrops.In this paper,the finite element software ANSYS/LS-DYNA was used to simulate dynamic response when the supplying cabin was subjected to drop impact.Then,judge the feasibility of the design of the structure of the cabin.Comparing with the traditional method,this method is more economic,time-saving and advanced. |
