本文提出了一种设计刚性、可予应力张拉桁架天线的方法。该方法结合了一个基本规则的建设刚性桁架的索网结构的一个有效的找形方法。首先，为给定的支撑结构创建静定张力桁架配置。然后，张拉桁架的预应力几何形状生成使用找形方法。通过对三种不同支承结构的张拉桁架天线的分析，验证了该方法的优越性。
An approach for the design of stiff, prestressable tension truss antennas is presented. The approach combines a basic rule for the construction of stiff trusses with an efficient form-finding method for cable net structures. First, statically determinate tension truss configurations for a given supporting structure were created. Then, prestressable geometries of the tension trusses were generated using the form-finding method. Three tension truss antennas with different supporting structures were analysed to demonstrate the advantages of the approach.
