【内容摘要】:使用遗传算法对神经网络阈值和权值进行优化,通过适应度函数可以达到选取最优权值和阈值的目的。此方法可以探寻得到螺纹钢微量元素含量与断后伸长率、抗拉强度和屈服强度力学性能之间关系,其优化后的最佳含量与生产实际比较贴近,有助于对螺纹钢成分优化方案的研究。

[abstract of content] :The genetic algorithm is used to optimize the threshold and weight of neural network, and the optimal weight and threshold can be selected through fitness function. This method can explore the relationship between the content of trace elements in the rebar and the mechanical properties of break elongation, tensile strength and yield strength, and the optimum content after optimization is close to the actual production, which is helpful to the study of the optimized composition of rebar components.

[key words] : genetic algorithm, BP neural network, rebar composition, optimization scheme
