| 摘 要： | 结构动力学分析是大口径空间天线研制工作的重要组成部分。本文将多级剪刀机构与复式螺旋机构组合,提出了一种新型的径射状可展天线反射器结构,设计了18 m口径的天线反射器,并建立了工作状态时的天线反射器结构有限元模型。采用ANSYS软件计算了径射状天线反射器的固有频率、谐响应和冲击响应,并研究了索网拉力、材料阻尼等对冲击响应的影响规律,为该天线的结构参数优化和阻尼设计提供了依据。

| Abstract: | Structural dynamics analysis is important for developing a big-caliber space antenna.Combining a multistage shear mechanism with a twin-screw thread mechanism,the paper presented a new big-caliber space antenna with radial deployable ribs,designed an antenna reflector with the caliber of 18 meters and established its finite element model under working conditions.It also calculated its inherent frequency,harmonic response and impact response using the ANSYS and studied the influence of cable strain and damping of materials on impact response,which is of help for the antenna′s structural parameter optimization and damping design. |
