摘要
机械加工过程中不同工序间复杂耦合关系会导致加工效率不高。为了解决这个问题,构建了考虑效率最大化的机械加工工艺路线多目标优化模型。以涿州机械厂加工的液压仰拱栈桥、衬砌台车为例,分析液压操作系统、数控切割机的能耗特性。以加工能耗低、加工时间短为目标,建立优化目标函数,计算总能耗和总耗时。设定液压操作系统和数控切割机加工过程约束条件,构建多目标优化模型,并利用帝国竞争算法进行模型求解。结果显示,该模型能耗和时间均优化时,加工效率最高为96%,说明使用该模型加工效率较高。
Due to the complex coupling relationship between different processes in machining process,the machining efficiency is not high.In order to solve this problem,a multi-objective optimization model of machining process route considering efficiency maximization is constructed.Taking the hydraulic inverted arch trestle and lining trolley processed by Zhuozhou Machinery Factory as an example,the energy consumption characteristics of hydraulic operating system and NC cutting machine are analyzed.With the goal of low processing energy consumption and short processing time,the optimization objective function is established to calculate the total energy consumption and total time consumption.This paper set the constraints of hydraulic operating system and NC cutting machine machining process,build a multi-objective optimization model,and solve the model by using imperial competition algorithm.The experimental results show that when the energy consumption and time of the model are optimized,the maximum processing efficiency is 96%,indicating that the processing efficiency of the model is high.
