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 local optimal design method of transmission tower based on ant colony algorithm is proposed to solve the problem of structure cross section, topology, shape and layout optimization simultaneously. On the basis of unifying all the optimization variables, the four types of optimization problems at different levels are unified into a standardized traveling salesman problem that is suitable for solving ant colony algorithm. Then the optimization design and programming of transmission tower structure are implemented by using MATLAB system platform. The actual project is an example to verify the local optimization method. The results show that the proposed method can not only solve the cross sections, topologies, shapes and layout optimization problems of transmission towers in a simple and efficient way, but also have very good practicability and versatility. The proposed method is expected to be applied to the complete transmission tower structure optimization design in.
