中文摘要:
      目的 实现可空投系留平台软着陆, 为优化可空投系留平台的隔振缓冲设计提供理论参考。方法 将可空投系留平台等效为二自由度非线性隔振缓冲系统, 在Matlab环境中,采用四阶龙格-库塔方法, 对可空投系留平台跌落冲击响应进行数值仿真, 并分析系统参数对系留平台中继模块空投跌落冲击响应的影响。结果 得到动态响应数据和曲线, 避免了大量破坏性试验, 得到不同参数条件下的跌落冲击仿真结果。结论 根据隔振缓冲仿真系统的动态响应规律, 可对隔振缓冲包装的安全性进行评估, 实时修改设计参数, 有效地提高隔振缓冲包装设计的精确性和经济性。
英文摘要:
      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.
