某星载双反射抛物面天线轻量化设计

为了解决某星载双反射抛物面天线超重的问题，文中采用力学仿真和试验的方法对其进行了研究。首先，采用铝合金材料对天线进行结构设计，并计算整个天线的重量，结果显示不满足项目重量指标要求；然后，基于碳纤维复合材料的特性，对模型进行结构优化设计，使重量指标满足项目要求，同时进行力学仿真分析，校核天线的结构强度；最后，通过振动试验验证了这种轻量化设计的可行性。文中的研究思路和方法为星载双反射抛物面天线的轻量化设计提供了参考。

Weight Reducing Design of a Spaceborne Double Reflection Paraboloid Antenna

The mechanic simulation and test are carried out to solve the overweight problem of a spaceborne double reflection paraboloid antenna in this paper. First, a three-dimension model of the antenna is designed with aluminum alloy material and weight of the whole antenna is calculated, but the weight does not meet the requirements of index. Then, optimization design of the model is carried out based on characteristics of the carbon fiber composites. Meanwhile, the structure strength of antenna is verified by mechanic simulation analysis. Finally, feasibility of the optimization design is verified by vibration test. The research ideas and methods in this paper provide a reference for the weight reducing design of spaceborne antennas.
