摘要
采用微观遗传算法和有限元模拟方法开发了锻造过程微观组织优化程序,对圆柱体的镦粗成形进行了面向微观组织优化的预成形设计,取得了较好的优化效果。根据镦粗实例的预成形优化结果,进行了相应的实验研究,晶粒尺寸及其分布与优化结果比较吻合。
Using the genetic arithmetic and FEM simulation, the software for optimal design method of the microstructure in forging process was developed. The preformed design of the cylinder upsetting forging process realized the optimization of the final microstructure. According to the optimal results, an experiment was designed. The experimental results were in accordance with the optimal results in the grains size and its distribution.
