摘要
采用遗传算法对直埋水平弯头进行优化设计。以弯头造价最低为优化目标,采用惩罚函数法处理复杂的非线性约束,求出最优的曲率半径和壁厚,结果可直接应用于工程设计。
The optimum design of directly buried horizontal elbow is performed using genetic algorithm. Taking the lowest cost of elbow as the objective, the complex nonlinear constraints are treated using penalty function method, and the optimum curvature radius and pipe wall thickness are calculated. The results can be directly used in engineering design.
