| 摘 要： | 为了解决星载天线的大口径与运载工具整流罩有限体积,以及星载天线的重量与卫星平台和运载工具承载能力之间的矛盾,充气可展开结构技术是非常理想的选择。为实现高精度反射面,针对平面-抛物面型充气可展开天线反射面,进行弹性力学分析,得到反射面与充气气压、薄膜材料、边界条件之间的关系,以及形面和抛物面间存在的M形误差。在此基础上,探讨了天线在轨时温度变化对反射面形面的影响,提出了消除这种影响的两种方法。利用ANSYS分析结果对理论解进行验证,结果吻合。

| Abstract: | To solve the problem between limited volume of the rocket mantles and large caliber requirement of antenna and the problem between carrying capacity of rocket and large weight of antenna,the inflatable antenna structure technology is one of the best choice.Afterward,to obtain high precision of inflatable reflector,one of figuration theories which is titled as plan- parabolic reflector,was investigated.The elastic theory analysis was carried out and the relationship between reflector shape and inflatable pre... |
