| 摘 要： | 输电铁塔是大型空间桁架结构。采用广义变量近似方法研究了桁架结构的形状优化问题。通过选取合适的广义中间变量，可有效地提高近似质量，结构分析次数可降低到与优化准则法同一数量级的水平。近似问题由约束变尺度法求解，原问题的解由近似问题的解的序列逐步逼近。

| Abstract: | Transmission tower is a large structure of space truss. In this paper, approximation concept is introduced to investigate the shape optimization. By choosing appropriate generalized intermediate variables the quality of approximation could be improved effectively and the number of structural analysis will be decreased to the same order of the optimization criteria. The approximated issue is solved by variable metric method for constrained optimization (CVM). The solution of the original optimization question is acquired through solving a series of approximated issues. |
