前言天线罩是用来减轻周围环境对天线、天线座影响的防护设备。消除风负荷的影响,使天线结构各部件的尺寸减小,从而减小了反射体俯仰及天线座方位转动的转动惯量。较小的转动惯量及风力矩的消除能使传动设备的尺寸有一定的减小。φ17米截球型双层蜂窝夹层结构玻璃钢天线罩安装在舰艇上,使用环境条件极端恶劣,风速高达72米/秒。高精度的电讯性能要求限制了天线罩的结构尺寸,提出了较高的均匀性要求。而天线罩仅仅固定在一个较小的圆环上,支承条件十分不利。为了既保证天线罩的电讯性能指标,而又满足结构上的刚度、强度要求,必须对天线罩在各种荷载作用下进行力学计算分析。在天线罩所承受的荷载中,风载荷是主要荷载。为了其实
Preface Radome is used to reduce the impact of the surrounding environment on the antenna, antenna protection equipment. By eliminating the influence of wind load, the size of each component of the antenna structure is reduced, thereby reducing the moment of inertia of the reflector pitching and the azimuth rotation of the antenna base. The smaller moment of inertia and the elimination of wind torque can reduce the size of the transmission equipment to some extent. φ17-meter interception-type double honeycomb sandwich structure FRP radome installed on the ship, the use of extreme environmental conditions, the wind speed up to 72 m / s. High-precision telecommunications performance requirements limit the size of the radome structure, put forward a higher uniformity requirements. The radome is only fixed on a smaller ring, the supporting conditions are very unfavorable. In order to ensure the telecommunication performance index of the radome and meet the structural rigidity and strength requirements, the radome must be subjected to mechanical calculation and analysis under various loads. Among the loads borne by the radome, the wind load is the main load. In fact
