【摘要】：为降低电弧焊加工过程的能量消耗、减少环境排放,对电弧焊加工节能高效工艺参数优化问题进行了研究。建立了电弧焊加工过程电能消耗目标函数及热效率目标函数,在考虑焊接质量及设备、工艺对等实际约束的基础上,建立了以焊接电流和焊接速度为优化变量,以最小电能消耗(节能)和最大热有效利用率(高效)为优化目标的多目标优化模型;利用自适应进化梯度小生境遗传算法对模型进行了寻优求解;通过某阀座密封面手工电弧焊加工实例对所建模型及方法的可行性和有效性进行了验证,并将优化结果与实际结果及传统遗传算法的结果进行了比较分析。
[Abstract]:In order to reduce energy consumption in arc welding process and reduce environmental emissions, the optimization of energy saving and high efficiency process parameters in arc welding process was studied. The electric energy consumption objective function and thermal efficiency objective function of arc welding process are established. On the basis of considering welding quality and equipment and equivalent practical constraints of process, the welding current and welding speed are taken as optimization variables. A multi-objective optimization model with minimum energy consumption (energy saving) and maximum thermal efficiency (efficient) as the optimization objective is proposed, and the adaptive evolutionary gradient niche genetic algorithm is used to solve the model. The feasibility and effectiveness of the proposed model and method are verified by an example of manual arc welding for a seat sealing surface. The results of optimization are compared with those of the actual results and the results of the traditional genetic algorithm (GA).
