摘要
大型地面雷达罩的结构设计通常以风载为控制载荷,现国内多以统一的抗风能力要求进行雷达罩的设计,而实际不同地区的基本风压有很大的差异,为此按照一定的原则对雷达罩的抗风要求进行适当分档是十分必要的。提出的三分档法经分析表明具有明显的经济价值,对提升罩体的电性能也有一定意义。进一步依据分档标准提出的全国区划结果可供产品订货方、供应商和独立设计单位参考。
The limit load for structure design of large ground radome is usually wind load.Now the requirements of wind resistant ability for radome design are often taken to be the same nationwide.However,in practice,there are great differences with basic wind pressure in different regions.Therefore,the wind resistant ability should be divided into appropriate several grade division according to certain principles.The 3 grades division method,which is proposed in this paper,shows that it has obvious economic value and has certain significance to the improvement of electrical properties.Further the region division based on the standards of classification hope to attract all of the product ordering party,supplier and independent design company's attention.
