| This paper introduced airdrop cushioning packaging design, including wire rope vibration isolation and cushioning system design and foam pad buffer system design, in order to select appropriate cushioning material and buffer form, to ensure safety and reliability of airdrop. Targeting at the two impact conditions of materials during airdrop, namely parachute opening and landing, finite element analysis and calculation were conducted. And airdrop cushioning packaging design was conducted according to the maximum impact in the two conditions. The maximum stress of touchdown instant was 4.8 MPa, and the maximum displacement was 0.666 mm. The maximum stress of the rebound process was 13.3 MPa, and the maximum y directional displacement was 5.49 mm. The shock isolation calculation and buffer pad structure check both passed. The drop packing buffer scheme using an internal foam pad buffer system and an external wire rope vibration isolation system had excellent buffer performance, and could meet the design requirements of maintaining packaged materials intact after airdrop. |
