| 摘 要： | 针对水射流切割工艺中过程参数的优化选择进行了研究,考虑切割速率和比能消耗两个目标函数,采用改进非支配排序遗传算法(NSGAII)研究了多目标优化设计问题。根据Pareto最优解形成决策矩阵,基于信息熵法得到属性的权重,利用逼近理想解的排序方法(TOPSIS)进行多属性决策。讨论了一个木材切割过程中参数优化的算例,分析了喷嘴直径、间隙、压力等参数对切割速率和比能消耗的影响。综合采用多目标优化和多属性决策技术,可以迅速选择生产过程中的系统参数。

| Abstract: | Water jet machining(WJM)is a special machining method using high-pressure high-speed water(pure water or water with additives)to impact the work piece with the action of suspended abrasive in the water for cutting,pouching,crushing or surface material removal.Multi-objective optimization and multi-attribute decision making of process parameters is evaluated.A hybrid approach is proposed for process system optimization.First,a Non-dominated Sorting Genetic Algorithm II(NSGA II)is employed to approximate the ... |
