【摘要】：我國是制造業(yè)大國,而制造業(yè)仍處于以高能耗、高污染、高排放為主要特征的粗放型發(fā)展模式,制造業(yè)能耗占全國能耗總量比例相當大;能耗量大、能量效率低、碳排放量大是我國制造業(yè)當前面臨的嚴峻問題。數控加工系統(tǒng)是由數控機床、工件、刀具、工裝夾具以及各種輔助設施構成的典型制造系統(tǒng),在數控加工過程中涉及大量能量和物料消耗。隨著我國制造業(yè)數控化率的進一步提升,迫切需要從系統(tǒng)的層面對數控加工系統(tǒng)的能量消耗特征以及優(yōu)化模型展開研究,實現系統(tǒng)能效的提升。本論文結合國家高技術研究發(fā)展計劃(863計劃)課題“機床產品機械加工制造系統(tǒng)能效優(yōu)化提升技術及應用”(2014AA041506)和國家自然科學基金面上項目“面向廣義能量效率的數控加工工藝規(guī)劃理論與方法研究”(51475059)等課題,從廣義能量效率的角度出發(fā),對數控加工系統(tǒng)優(yōu)化模型及方法展開研究。首先,在分析數控加工系統(tǒng)能量消耗特點的基礎上,提出數控加工系統(tǒng)廣義能量消耗的概念,并從直接能耗和間接能耗兩個方面對數控加工系統(tǒng)能量消耗進行分類與計算,建立數控加工系統(tǒng)的廣義能耗模型;進而,提出廣義能量效率的概念,并通過能量利用率和比能兩種形式來進行表達;基于所提出的數控加工系統(tǒng)廣義能耗模型,從工藝參數、工藝路線和車間作業(yè)調度三個層次出發(fā),建立面向廣義能量效率的數控加工系統(tǒng)能效優(yōu)化框架模型。其次,針對數控加工系統(tǒng)工藝參數選擇對能量消耗的影響,構建面向工藝參數的數控加工系統(tǒng)廣義能效模型;基于此,以加工過程時間和能效作為優(yōu)化目標,建立集成數控加工系統(tǒng)廣義能效與加工時間的工藝參數多目標優(yōu)化模型,采用改進的非支配遺傳算法對該模型進行求解,并采用仿真實驗的方式揭示工藝參數與數控加工系統(tǒng)廣義能效的映射關系。以某長傳動軸的工藝參數優(yōu)化過程,對所建立的模型進行應用,以驗證面向廣義能量效率的工藝參數優(yōu)化模型的節(jié)能性。再次,在采用特征元素對數控加工工藝路線進行表達的基礎上,針對工藝路線與能量消耗的關系,建立面向數控加工工藝路線的廣義能效模型,并考慮以實現能效提升、時間效率提升為優(yōu)化目標,建立集成廣義能量效率與時間效率的數控加工系統(tǒng)工藝路線多目標優(yōu)化模型,并采用遺傳算法對該模型進行求解;以圓柱齒輪加工為例,對其數控加工工藝路線進行優(yōu)化分析,以實現能效提升。然后,針對數控加工車間作業(yè)調度問題對能量消耗的影響,建立面向車間作業(yè)調度的數控加工系統(tǒng)廣義能效模型;以車間作業(yè)調度的廣義能量效率與最小完工時間為目標,建立面向廣義能效的數控加工車間作業(yè)調度問題的多目標優(yōu)化模型,并采用遺傳算法進行求解。最后,介紹了一種面向廣義能量效率的數控加工系統(tǒng)能效優(yōu)化支持系統(tǒng)。該系統(tǒng)可以輔助用戶查詢、收集、管理零件加工工藝信息以及加工過程中能效信息,為相關人員提供一套加工過程工藝參數、工藝路徑和調度管理的優(yōu)化方案。
[Abstract]:China is a large manufacturing country, and the manufacturing industry is still in the extensive development model with high energy consumption, high pollution and high emission. The energy consumption of manufacturing industry accounts for a large proportion of the total energy consumption in the country, the energy consumption is large, the energy efficiency is low, and the carbon emission is large. The typical manufacturing system composed of workpiece, tool, fixture and all kinds of auxiliary facilities involves a lot of energy and material consumption in the process of NC machining. With the further improvement of the numerical control rate of China's manufacturing industry, it is urgent to study the energy consumption characteristics and the optimization model of the NC machining system from the system layer. This paper combines the national high technology research and development plan (863 plan), "the technology and application of energy efficiency optimization and upgrading of machine tool manufacturing system" (2014AA041506) and the National Natural Science Foundation Project "Research on the theory and method of NC machining process planning for the generalized energy efficiency" (51475 059) on the basis of analyzing the energy consumption characteristics of NC machining system, the concept of generalized energy consumption of NC machining system is put forward on the basis of the characteristics of the energy consumption of NC machining system, and the energy dissipation of the NC machining system is eliminated from two aspects of direct energy consumption and indirect energy consumption. The consumption is classified and calculated, and the generalized energy consumption model of NC machining system is established. Then, the concept of generalized energy efficiency is proposed and expressed through two forms of energy utilization and specific energy. Based on the proposed generalized energy consumption model of NC machining system, it is built from the three levels of process parameters, process route and job shop scheduling. The framework model of energy efficiency optimization for NC machining system with generalized energy efficiency is set up. Secondly, based on the influence of process parameters selection on energy consumption of NC machining system, a generalized energy efficiency model of NC machining system oriented to process parameters is constructed. Based on this, an integrated NC machining system is set up with the process time and energy efficiency as the optimization target. The multi-objective optimization model of the process parameters of generalized energy efficiency and processing time is used to solve the model by the improved non dominating genetic algorithm. The mapping relationship between the process parameters and the generalized energy efficiency of the NC machining system is revealed by the simulation experiment. The model is carried out by the optimization process of the working parameters of a long transmission shaft. The application is to verify the energy efficiency of the process parameter optimization model for the generalized energy efficiency. Thirdly, on the basis of the expression of the numerical control process route by the feature element, the wide sense energy efficiency model for the process route of NC machining is established, and the energy efficiency improvement is considered. In order to optimize the efficiency, the multi-objective optimization model of the NC machining system with integrated generalized energy efficiency and time efficiency is set up, and the genetic algorithm is used to solve the model. The cylindrical gear processing is taken as an example to optimize the process route of its NC machining to achieve energy efficiency improvement. Then, the numerical control processing is carried out. The effect of job shop scheduling problem on energy consumption, a generalized energy efficiency model of NC machining system for job shop scheduling is established, and the generalized energy efficiency and minimum completion time of job shop scheduling are taken as the objective, and a multi-objective optimization model for the job scheduling problem of NC machining shop for generalized energy efficiency is established, and genetic calculation is adopted. The method is solved. Finally, a kind of energy efficiency optimization support system for NC machining system for generalized energy efficiency is introduced. This system can assist users to query, collect, manage parts processing technology information and energy efficiency information in processing process, and provide a set of processing process parameters, process path and scheduling management for the related personnel.
