摘　　要：星载雷达在发射和飞行过程中需要承受多种振动和冲击,其所处的复杂环境条件对雷达结构件的设计提出了很高的要求,传统的以经验为主的结构设计流程由于存在设计周期长,研制成本高,设计结果不能最优化等缺点,难以满足要求。文中提出了基于数值模拟的新的优化设计流程,针对星载雷达发射机中承载合成器和分配器的支撑架结构进行了系统的动力学仿真分析,并根据分析结果优化设计,取得了较好的效果,为星载雷达结构设计提供了有价值的参考,研究结果表明新设计流程可以得到可靠性更高的产品,并能大大缩短产品的设计周期,降低试制成本,对星载雷达产品的设计生产具有重要的借鉴意义。During launch and flight,the spaceborne radar has to endure a variety of vibration and shock.Due to the complicated environmental conditions,the structural components of radar need to be well designed.The traditional structure design process based on experiences is difficult to meet the requirements because of the long design cycle,high costs and other shortcomings.A new optimized design process based on numerical simulation was presented in this paper,and system dynamics analysis of the supporting frame was carried out.The supporting frame was used to support the synthesizer and distributor of radar transmitter.Subsequently,optimized design based on the analysis results was carried out and a better structure was obtained,which can provide some valuable information for radar structure design.The research results showed that by using the new design process,more reliable products can be obtained and the product design cycle can be greatly shortened,and the costs can be reduced.The new design process has an important reference to the design of space-borne radar products.
