从降低风荷的角度 ,设计了大型射电望远镜的悬挂馈源舱体外形及舱内框架支撑结构 .对馈源悬挂系统进行了非线性有限元静力分析 ,结合优化方法 ,联立迭代求解了馈源舱体的位置、姿态、悬索的悬链线、张力和长度 ,为进一步系统地模拟分析非线性馈源悬挂系统在随机风荷作用下的风振响应奠定了基础 . From the perspective of reducing the wind load, the shape of the suspended feed cabin and the support structure of the cabin in the large radio telescope are designed.The nonlinear finite element static analysis of the feed suspension system is performed, and combined with the optimization method, The position and attitude of the feed cabin, the catenary, tension and length of the cable stayed the foundation for the further systematic simulation of the wind-induced vibration response of the nonlinear feed suspension system under random wind loads.
