| 目的 研究空投货物出舱姿态变化过程，为确定最佳的捆绑货物重心位置提供依据。方法 基于Ansys/LS-DYNA软件平台，以某型重装空投系统为例，采用数值模拟的方法研究不同情况下货物出舱姿态的微观变化过程，包括翻转角度和翻转速度随时间的变化情况，从而确定出最佳的捆绑货物重心位置。结果 对出舱速度为1 m/s时不同重心位置货物的翻转过程进行了数值分析，确定了该速度下最佳捆绑货物的重心位置。结论 捆绑货物重心位置对货物的出舱姿态有明显影响。采用数值模拟的方法对空投货物出舱姿态变化过程进行分析，能够得出逼近实际且较为精确的解。 |

| The work aims to study the changing process of airdrop cargo extraction posture and provide references to determine the best binding part of the gravity center position of cargo. Based on the Ansys/LS-DYNA software platform and with a certain type of heavy equipment airdrop system as example, the microcosmic changing process of cargo extraction posture in different situations was researched by numerical analysis method, including the change of turn-over angle and turn-over speed as time changes. Then the best binding part of the gravity center position of cargo was determined. The numerical analysis was done on the turn-over process of cargo with different gravity center positions at the extraction speed of 1 m/s, and the best binding part of the gravity center position of cargo was determined. In conclusion, the binding part of the gravity center position of cargo has a significant influence on the cargo extraction posture. Analysis of the changing process of airdrop cargo extraction posture by numerical simulation method can get accurate and close-to-actual solutions. |
