摘要
提出了一种可同时求解结构截面、拓扑、形状和布局优化问题的基于蚁群算法的输电塔结构局部优化设计方法。在统一所有优化变量的基础上,将4类不同层次的优化问题统一为适用于蚁群算法求解的标准化旅行商问题,再采用MATLAB系统平台实现输电塔结构的优化设计和程序化,并以某实际工程为算例对局部优化方法进行验证。结果表明:提出的方法不仅可以简单高效地求解输电塔结构塔身局部的截面、拓扑、形状和布局优化问题,而且具有非常好的实用性和通用性,有望应用于完整的输电塔结构优化设计中。
A new local optimal design method of transmission tower structure,which could apply in cross-section,topology,shape and layout optimization problems,was proposed based on ant colony optimization（ACO）algorithm.With unifying the multiple type variables into discrete variables,the four optimal problems with different levels were transformed into the standardization traveling salesman problem,and it also was realized in programmed control by MATLAB system platform,then an actual example was calculated to verify the local optimal design method. The results show that the proposed optimal design method has a good performance in cross-section,topology,shape and layout optimal problem with generality and programmed pattern,and it also has a good application prospect in optimal design of transmission power structure.
