| 摘 要： | 用遗传算法处理设计变量为杆件中离散型材截面的桁架最轻重量优化问题。将离散的截面参数用二进制的遗传因子表示，利用染色体的遗传繁殖和自然淘汰等特点，可以在较广的参数域内对优化解进行搜索。并将满强度设计与遗传算法相结合，加速了收敛速度。算例表明，在不大的计算量下可获得相当良好的全局性优化解。

| Abstract: | his paper attempts to design optimization of a space truss by using the genetic algorithm.The design variables are the separate sectional area of a bar and the optimizing objective is the least weight.Separate parameters are replaced by the genetic codings of binary numbers.Characters of the genetic reproduction and natural selection are used to search for the optimal solution in a wider design parameter region.The convergence is accelerated by combining the genetic algorithm with full strength design.The computational example indicates that this method can obtain a better solution at a less cost. |
