Airdropped Impact Effect of Airdropped Tethered Balloon Platform

Objective To achieve soft landing of tethered balloon platform and to provide reference for the design of isolating and cushioning of tethered balloon platform. Methods The airdropped tethered balloon platform was equivalent to a two-degree-of-freedom nonlinear vibration system. Numerical simulation on airdropping impact of airdropped tethered balloon platform was conducted with the method of Runge-Kutta in Matlab environment. The effects of the system parameters on the airdropped impact effect of airdropped tethered balloon platform were also analyzed. Results The dynamic response data and curve in Matlab environment were obtained, and destructive tests were avoided. The parameters could be easily modified, and the airdrop simulation under different parameters were obtained. Conclusion The security of vibration isolating and cushioning pack was assessed according to the dynamic response rules of vibration isolating and cushioning simulation system. The design parameters were real-time revised, which effectively improved the accuracy and economy of the design of vibration isolating and cushioning pack.
