摘　　要：天线罩作为天线设备的防护装置,在满足电性能透波需求的同时,也应满足结构力学性能。以某型空间骨架球形雷达天线罩为研究对象,基于ANSYS有限元分析软件,进行风载荷、雪载荷及自重载荷下的结构力学仿真,计算得出天线罩在载荷作用下的应力值及位移量等。仿真结果表明,该天线罩的最大位移响应和稳定性响应均满足设计要求,验证了天线罩在风载荷、雪载荷及自重载荷下的结构安全性。As a protective device for antenna equipment,the radome should not only meet the electrical performance and wave transmission requirements,but also meet the structural mechanical performance.Taking a certain type of spatial skeleton spherical radar radome as the research object,based on ANSYS finite element analysis software,structural mechanics simulations are conducted under wind load,snow load,and self weight load,and the stress and displacement values of the radome under load are calculated.The simulation results show that the maximum displacement response and stability response of the radome meet the design requirements,verifying the structural safety of the radome under wind load,snow load,and self weight load.
