摘要
介绍了大射电望远镜(FAST)30m模型主动反射面支承结构——整体索网结构,根据现场条件提出了三种可行的施工方案,并利用ANSYS的生死单元技术模拟索网张拉过程.通过分析、对比确定了最优方案,并以此指导了实际施工,为FAST500m原型的建造积累了经验.
This paper introduces the cable-net structure supporting the reflector of FAST （Five-hundredmeter Aperture Spherical Telescope） 30m model, gives three feasible schemes for construction according to the site conditions, and uses the ANSYS birth and death element to simulate the construction process. Based on the analysis, the final scheme is used to guide the construction. The research here provides much important experiences for the construction of FAST in the future.
