摘要: 面向空间天线大型化、轻量化需求,设计了杆膜一体卷曲展开薄膜阵列天线可展结构,实现了我国首个薄膜阵列天线在轨验证。首先,采用瑞利-里兹法建立了考虑张力作用的薄膜天线一阶弯、扭、摆振动频率近似解析模型,推导了薄膜天线框架结构的一阶扭转振动频率近似解,指导了薄膜天线结构动力学特性的快速分析与参数设计,相比于非线性有限元法,具有高效便捷的特点。其次,研究了薄膜天线主梁截面半径、框架长宽比、张力大小等特性参数对天线振动频率的影响,给出了结构参数的优选范围,通过仿真和试验方法验证了参数设计的合理性。最后,介绍了薄膜天线在轨展开验证情况,试验表明在卫星姿态机动扰动下天线结构保持稳定,验证了结构设计的可行性。

Abstract: In order to meet the requirements of large size and light weight of spaceborne antennas, the configuration of a roll-out membrane array antenna is developed, which has been the first thin-film antenna deployed on-orbit in China. Firstly, the fundamental bending, torsional and pendulum vibration frequency approximate analytical model considering the tension effect is established by the Rayleigh-Ritz method, and the fundamental torsional vibration frequency of the antenna frame structure is derived, which guided the rapid analysis and parameter design of the structural dynamics of the membrane antenna. The model has the characteristics of high efficiency and convenience compared with the nonlinear finite element analysis method. Secondly, the influence of characteristic parameters, such as primary beam cross-sectional radius, frame aspect radio and tension force, on the vibration frequency of the antenna is studied, the optimal ranges of structural parameters are given, and the effectiveness of the parameter design is verified by simulation and structural modal test. Finally, the on-orbit deployment demonstration of the roll-out membrane array antenna is introduced. The experiment show that the antenna structure could remain stable under the disturbance of satellite attitude maneuvering, which verified the feasibility of structural design.

Key words: spaceborne antenna, deployable membrane array antenna, configuration design, on-orbit demonstration
