摘　　要：不同于一般机动式雷达,某固定式电子系统频段更宽,天线口径更大,天线内设备日常维护量、维护范围更大,设备抗风指标要求更高;后端电子设备综合布置在若干大型机柜中,热流密度大,需考虑大型液冷机柜结构设计问题和机柜内部设备散热问题;设备工作在海边,需采取有效措施实现全机防护要求;系统要经历多阶段测试,需频繁转场至各工作场所工作,宜采取有效技术手段实现多阵地灵活架设。本文根据某类大型产品的研制经验,讨论了该类产品结构总体设计方法。Different from normal movable radar,a multi-band fixed electronic equipment has larger antenna aperture wide-range frequency antennas resulting in large dimension and heavy maintenance tasks for devices in the antenna.Meanwhile,the requirement for anti-wind capability of this equipment is much higher than that of conventional radar.The back-end electronic devices are arranged in several water cooling cabinets.So the structure of cabinets should be designed especially to solve the heat dissipation problem of the devices with high heat flux.Furthermore,effective technical means should be used for protecting equipment from corrosion considering seaside circumstance.At last,a variety of tests will be carried out for the equipment,which means it needs to be transported to different sites,so effective technical means should be used in erection.This paper discusses the method of structural design above according to the experiences from some products.
