The article describes the shape of wind load on the radome surface and analyzes the internal force of the radome with nonmomental theory of shell , stresses and stability with theoretic formula , equivalent modulus of elasticity and thickness of a - sandwich - composite structure 摘要针对雷达罩易受风荷载作用发生破坏的情况,本文从截球形雷达罩表面的风荷载分布形态出发,采用无矩理论对雷达罩内力进行了分析计算,从理论上对模型进行了强度和稳定性分析,并着重阐述了a型复合材料夹芯结构的等效弹性模量和厚度的计算方法。
The steel framework occupies a large portion of weight in the csicdc for its high density , and the foam sandwich structure occupies a large portion of volume in the csicdc and the costs is very high , therefore the optimum design work about the csicdc was focused on the steel framework and foam sandwich structure 由于钢骨架密度大,其重量在司机室中所占比例大,同时玻璃钢泡沫夹芯结构材料用量大且成本高。因此,混杂结构司机室优化设计工作主要围绕钢骨架和玻璃钢泡沫夹芯结构展开。
