电源组件作为雷达产品中的供电装置，其供电稳定性及可靠性直接影响雷达产品性能。对于电源组件的结构设计而言，不仅要保证电源器件、模块得到有效可靠的支撑固定，还要保证其有良好的散热途径，进而控制元器件工作时的结温及壳温稳定在额定值范围内。本文对某型雷达产品的电源组件结构进行了基于有限元的动态响应及热仿真分析，验证了结构设计的有效性，并根据仿真结果对设计方案进行了局部改进。%As the power supplier of radar , electrical source ’ s stability and reliability will directly af-fects radar performance .For electrical source ’ s structural design , not only the credible fixing is provided for the electrical source component , but also the good pathway of heat conduct is needed , to control the e-lectrical source component ’ s work temperature .In this paper , based on finite element method , the dy-namic response and thermal simulation are conducted for electrical source ’ s structure of radar production , the validity about structural design is testified , and the design is partially improved according to the simu-lation result .
