摘 要:
针对周边桁架可展开天线索网反射面的特点,以结构的几何外形为已知量(设计者给定),给定一组初始预应力为迭代初值,并给模型的各节点施加一个小△的位移量,迭代反算求解出一组预拉力以及与之相应的几何参数,即可确定网面的初始平衡态,并通过ANSYS反算验证。算例表明该法简单实用。[著者文摘]

Abstract:
Considering the flexible cable net deployable antenna, with the known parameters of the structure geometry and assigned a small displacement for the model, the initial equilibrium state of the net can be determined by using ANSYS iteration instead calculating as a group of pre-stressed forces were given. The numerical results have shown the validity of the methods.[著者文摘]
