【摘要】：我國是世界機(jī)床制造大國，機(jī)床消費(fèi)量和保有量居世界第一，但我國機(jī)床服役周期長，，老化嚴(yán)重。僅在“十二五”期間，將有100多萬臺(tái)機(jī)床面臨各種形式的報(bào)廢。機(jī)床再制造是一種充分利用現(xiàn)有廢舊機(jī)床資源的機(jī)床制造新模式，具有顯著的節(jié)能、節(jié)材、減少環(huán)境排放的效果，是解決我國量大面廣的廢舊機(jī)床的有效方式，符合我國循環(huán)經(jīng)濟(jì)和低碳經(jīng)濟(jì)的發(fā)展要求。廢舊機(jī)床再制造性評(píng)估與再制造工藝方案決策是機(jī)床再制造關(guān)鍵技術(shù)之一，迫切需要相關(guān)理論基礎(chǔ)的支持。 本文結(jié)合“十二五”國家科技支撐計(jì)劃課題“中小型機(jī)床再制造生產(chǎn)技術(shù)開發(fā)及產(chǎn)業(yè)化應(yīng)用示范”（課題編號(hào)：2006BAF02A20）及國家自然科學(xué)基金“多壽命特征驅(qū)動(dòng)的廢舊零部件再制造工藝資源配置”（基金編號(hào)：51205295）等項(xiàng)目對(duì)廢舊機(jī)床再制造性評(píng)估和再制造工藝方案決策方法展開研究，為實(shí)施機(jī)床再制造提供技術(shù)支持。主要研究內(nèi)容有： （1）在分析技術(shù)性、經(jīng)濟(jì)性和環(huán)境效益對(duì)機(jī)床再制造性的影響程度的基礎(chǔ)上，結(jié)合我國機(jī)床再制造發(fā)展現(xiàn)狀，得出再制造成本是影響機(jī)床再制造性的關(guān)鍵因素。其次，針對(duì)機(jī)床失效特征多樣性導(dǎo)致再制造成本具有差異性的問題，運(yùn)用作業(yè)成本法分析出不同失效特征機(jī)床的再制造成本，并將機(jī)床失效特征和對(duì)應(yīng)的再制造成本作為案例進(jìn)行存儲(chǔ)。通過檢測(cè)某回收機(jī)床的失效特征，運(yùn)用實(shí)例推理技術(shù)在案例庫中檢索相似案例，預(yù)測(cè)機(jī)床再制造成本。最后，結(jié)合再制造機(jī)床的稅費(fèi)、運(yùn)行保證成本等費(fèi)用及設(shè)定的市場(chǎng)目標(biāo)利潤率，建立廢舊機(jī)床再制造性評(píng)估模型。 （2）以零部件失效數(shù)據(jù)和表征零部件性能退化的特征指標(biāo)數(shù)據(jù)為基礎(chǔ)，聯(lián)合威布爾分布和人工神經(jīng)網(wǎng)絡(luò)模型來評(píng)估廢舊零部件的剩余使用壽命。對(duì)于具有剩余使用壽命的廢舊零部件，以定量的方式分析其第一次壽命末期和剩余壽命末期的可靠性，并結(jié)合企業(yè)制定的零部件可靠性閾值，確定廢舊零部件的資源化策略，即再利用、再制造或再循環(huán)。 （3）建立了基于質(zhì)量功能展開、模糊線性回歸及0-1目標(biāo)規(guī)劃的再制造工藝方案決策模型。以零部件再制造的加工效率（時(shí)間）（T）、加工質(zhì)量（Q）、加工成本（C）、資源消耗（R）和環(huán)境排放（E）為決策目標(biāo)，不同工藝階段的工程技術(shù)參數(shù)為決策量，運(yùn)用質(zhì)量功能展開法建立決策目標(biāo)與決策變量的關(guān)聯(lián)函數(shù)以及決策變量之間的自相關(guān)函數(shù)，并運(yùn)用模糊線性回歸進(jìn)行參數(shù)求解。在此基礎(chǔ)上，通過0-1目標(biāo)規(guī)劃進(jìn)行優(yōu)化決策，得出最優(yōu)的再制造工藝方案。 （4）在以上理論和方法研究的基礎(chǔ)上，開發(fā)了廢舊機(jī)床再制造性評(píng)估與再制造工藝方案決策支持系統(tǒng)，對(duì)系統(tǒng)體系結(jié)構(gòu)、功能模塊設(shè)計(jì)及運(yùn)行流程進(jìn)行了闡述。 （5）對(duì)廣州機(jī)床廠實(shí)施機(jī)床再制造的實(shí)踐情況進(jìn)行介紹，重點(diǎn)以機(jī)床C6132A1為例，從再制造流程、再制造方案及再制造前后對(duì)比三個(gè)方面進(jìn)行分析。
[Abstract]:Our country is a big country of machine tool manufacture in the world. The consumption and possession of machine tool are the first in the world, but the service period of machine tool in our country is long and the aging is serious.During the five-year Plan period alone, more than 1 million machine tools will be scrapped in various forms.Machine tool remanufacturing is a new mode of machine tool manufacturing, which makes full use of the existing waste machine tool resources. It has remarkable energy saving, material saving and environmental emission reduction effect. It is an effective way to solve the problem of waste machine tool with large quantity and wide range in our country.In line with China's circular economy and low carbon economy development requirements.Remanufacturing evaluation and remanufacturing process decision are one of the key technologies of machine tool remanufacturing, which urgently need the support of relevant theoretical basis.This paper combined with the "12th Five-Year Plan" of the National Science and Technology support Program, "small and medium-sized machine tool remanufacturing technology development and industrialization application demonstration" (subject number: 2006BAF02A20) and the National Natural Science Foundation of China "Multi-Life characteristics driven waste Zero"Projects such as Resource allocation for component Remanufacturing process (Fund No.: 51205295) have studied the remanufacturing evaluation of waste machine tools and the decision-making methods of remanufacturing process schemes.Provide technical support for the implementation of machine tool remanufacturing.The main research contents are as follows:1) on the basis of analyzing the influence of technology, economy and environmental benefit on the remanufacturing of machine tool, and combining with the present situation of machine tool remanufacturing in China, it is concluded that the cost of remanufacturing is the key factor affecting the remanufacturing of machine tool.Secondly, aiming at the problem that the cost of remanufacturing is different due to the diversity of failure characteristics of machine tools, the cost of remanufacturing of machine tools with different failure characteristics is analyzed by using activity-based costing method.And the machine tool failure characteristics and the corresponding remanufacturing costs are stored as a case.By detecting the failure characteristics of a recovery machine tool and using case-based reasoning technology to retrieve similar cases in the case base, the cost of machine tool remanufacture is predicted.Finally, the remanufacturing evaluation model of waste machine tool is established by combining the tax and fee of remanufacturing machine, the cost of operation guarantee and the set market target profit rate.(2) based on the failure data of parts and the characteristic index data of performance degradation of parts, Weibull distribution and artificial neural network model are combined to evaluate the remaining service life of waste parts.For waste parts with residual service life, the reliability of the end of the first life and the end of residual life is analyzed quantitatively, and combined with the reliability threshold of parts and components established by enterprises, the strategy of recycling waste parts and components is determined.Reuse, remanufacture or recycling.3) the decision model of remanufacturing process scheme based on quality function expansion, fuzzy linear regression and 0-1 objective programming is established.The process efficiency (time, quality, cost, resource consumption and environmental emission) of parts remanufacturing is taken as the decision objective, and the engineering technical parameters in different technological stages are the decision quantity.The correlation function between decision objective and decision variables and the autocorrelation function between decision variables are established by using the quality function expansion method, and the parameters are solved by fuzzy linear regression.On this basis, the optimal remanufacturing process scheme is obtained by 0-1 objective programming.4) on the basis of the above theories and methods, a decision support system for remanufacturing evaluation and remanufacturing process of waste machine tools is developed. The system architecture, function module design and operation flow are described.This paper introduces the practice of machine tool remanufacturing in Guangzhou Machine tool Factory, and analyzes the process of remanufacturing, the plan of remanufacturing and the comparison between before and after remanufacturing, taking C6132A1 of machine tool as an example.
