摘　　要：工程结构优化设计是把力学和优化技术有机地结合,根据设计要求,使部分参与计算的量以变量出现,建立结构设计参数与结构重量、最大允许应力等的非线性关系,获得连续域蚁群算法求解结构优化问题所需的目标函数,用连续域蚁群算法进行寻优搜索运算,从而求出所需最优解。算例表明,连续域蚁群算法可求解多维连续优化问题,收敛速度快,且计算精度高,可用于工程结构优化设计。Based on designing requirements, Engineering Structural Optimized Design is to organically combine mechanics and optimizing methods, considering some of the parameters in calculation as variables, which leads to the establishment of the non-linear relationship between designing parameters and the weight of structures, as well as the maximum allowed stress. Thus, the objective function of solving structural optimizing problem using ant colony optimization for continuous domain is obtained and the optimized solution wiU be decided by using the ant colony optimization for continuous domain. Practical examples shows that the ant colony optimization for continuous domain can solve multidimensional continuous optimization problem with a fast convergence speed and a good precision in calculation, therefore it can be used for engineering design optimization.
