摘　　要：蚂蚁算法是近年来出现的仿生优化方法,该算法所具有的正反馈性、协同性及隐合并行性,使之成为一种具有广阔应用前景的优化算法。本文首先介绍了蚂蚁算法的基本原理及其编程方法,接着分别用五杆超静定桁架结构和齿轮减速器结构的优化问题对该算法进行考核。求解结果经与其它优化算法相对比,证实蚂蚁算法在求解机械结构优化问题上也可以获得较为满意的效果。Ant Algorithm is a bionic-optimization method, which has a capacious application foreground because of its properties of positive feeding-back, coordinating and implicating parallelism. The basic principle and the programming methods of the algorithm are firstly introduced in this paper. Then the algorithm was tested by two different mechanical structures, an over-constrained 5-bar truss and a gear wheel reducer system. Compared with some other algorithms, the optimal solution of the mechanical structure acquired by the Ant Algorithm has been proved to be more satisfactory.
