空间站空空支架天线抗力学环境设计与仿真分析

Design and Simulation Analysis of Resistance Environment for Space Station Air-to-air Support Antenna

空空支架天线是空间站核心舱的重要组成部分,担负着核心舱与来访飞行器对接时的通信任务,在全任务阶段,将受到不同的载荷冲击。文中对其发射阶段、入轨阶段、交汇对接阶段和分离阶段的载荷工况进行识别,并通过有限元分析、动力学仿真和计算校核,保证其抗力学环境设计满足要求,为后续产品详细结构设计、在轨成功展开和安全运行提供重要支撑。

The air-to-air support antenna is an important part of the core module of the space station.It undertakes the communication task when the core module is docked with the visiting aircraft. At the whole mission stage, it will be impacted by different loads. The load conditions at the launch stage, orbit entry stage, intersection & connection stage and separation stage are identified. The finite element analysis,dynamic simulation and calculation check are carried out to ensure that its resistance environment design meets the requirements. The result can provide an important support for subsequent product engineering design,successful deployment on orbit and safe operation.
