【摘要】：再制造是目前制造業(yè)中高價(jià)值機(jī)電產(chǎn)品循環(huán)利用的最佳方式,但傳統(tǒng)再制造工程中再制造毛坯所存在的不確定性一定程度上阻礙了再制造工程產(chǎn)業(yè)化的實(shí)現(xiàn)。本文針對(duì)再制造毛坯質(zhì)量及數(shù)量的不確定性問(wèn)題,闡述了主動(dòng)再制造的核心理念,從全生命周期的角度,以產(chǎn)品的性能參數(shù)作為評(píng)價(jià)指標(biāo),建立主動(dòng)再制造時(shí)域決策模型,提出了基于服役性能的主動(dòng)再制造時(shí)域決策方法。首先,闡述了機(jī)電產(chǎn)品主動(dòng)再制造的內(nèi)涵和核心理念,以及產(chǎn)品主動(dòng)再制造時(shí)域與零部件主動(dòng)再制造時(shí)域的內(nèi)涵及其相互之間的關(guān)系;研究了主動(dòng)再制造與產(chǎn)品服役性能之間的關(guān)系,以產(chǎn)品服役性能變化拐點(diǎn)作為主動(dòng)再制造最佳時(shí)機(jī),提出基于服役性能的主動(dòng)再制造時(shí)域決策方法。其次,通過(guò)分析零部件在服役過(guò)程中失效狀態(tài)以及產(chǎn)品服役性能的演變過(guò)程,建立在服役階段產(chǎn)品服役性能與零件失效狀態(tài)的量化映射關(guān)系,在此基礎(chǔ)之上,從全生命周期的角度,通過(guò)量化分析產(chǎn)品各關(guān)鍵零部件在四個(gè)階段(制造階段、服役階段、再制造階段、再生服役階段)的服役性能演化規(guī)律,建立零部件主動(dòng)再制造時(shí)域決策模型,并且基于多目標(biāo)優(yōu)化方法確定各關(guān)鍵零部件的主動(dòng)再制造時(shí)域。而后根據(jù)壽命匹配原則,對(duì)各關(guān)鍵零部件主動(dòng)再制造時(shí)域進(jìn)行匹配,使產(chǎn)品在全生命周期內(nèi)的技術(shù)性、經(jīng)濟(jì)性、環(huán)境性達(dá)到最佳,從而確定產(chǎn)品主動(dòng)再制造時(shí)域。最后,基于文獻(xiàn)及實(shí)驗(yàn)數(shù)據(jù)統(tǒng)計(jì),分析曲軸、連桿和氣缸的磨損對(duì)發(fā)動(dòng)機(jī)服役性能的影響,從而得到發(fā)動(dòng)機(jī)在服役階段、再生服役階段的性能演化規(guī)律;并通過(guò)計(jì)算發(fā)動(dòng)機(jī)在制造和再制造階段的能耗、環(huán)境排放、成本,構(gòu)建基于關(guān)鍵零部件磨損的發(fā)動(dòng)機(jī)再制造時(shí)域決策模型,而后根據(jù)多目標(biāo)優(yōu)化方法及匹配原則,確定發(fā)動(dòng)機(jī)的主動(dòng)再制造時(shí)域。
[Abstract]:Remanufacturing is the best way to recycle high value electromechanical products in manufacturing industry at present, but the uncertainty of remanufacturing blank in traditional remanufacturing engineering hinders the realization of remanufacturing engineering industrialization to a certain extent. In view of the uncertainty of the quality and quantity of remanufacturing blank, this paper expounds the core idea of active remanufacturing. From the point of view of the whole life cycle, taking the performance parameters of the product as the evaluation index, the time domain decision model of active remanufacturing is established. An active remanufacturing time domain decision method based on service performance is proposed. Firstly, the intension and core idea of active remanufacturing of electromechanical products and the relationship between the time domain of active remanufacturing and active remanufacturing of parts and components are expounded. The relationship between active remanufacturing and service performance is studied. Taking the inflection point of product service performance as the best time for active remanufacturing, a time domain decision method based on service performance is proposed. Secondly, by analyzing the failure state of parts in service and the evolution process of product service performance, the quantitative mapping relationship between service performance and failure state of parts is established. From the point of view of the whole life cycle, the evolution law of service performance of key parts in four stages (manufacturing stage, service stage, remanufacturing stage, regenerative service stage) is analyzed quantitatively. The time domain decision model of active remanufacturing of components is established, and the time domain of active remanufacturing of key parts is determined based on multi-objective optimization method. Then according to the principle of life matching, the time domain of active remanufacturing of key parts is matched to make the product achieve the best technology, economy and environment in the whole life cycle, and then determine the time domain of active remanufacture of the product. Finally, based on the statistics of literature and experimental data, the influence of wear of crankshaft, connecting rod and cylinder on engine service performance is analyzed, and the evolution law of engine performance in service stage and regenerative service stage is obtained. By calculating the energy consumption, environmental emission and cost of engine in manufacturing and remanufacturing stage, the time domain decision model of engine remanufacturing based on wear of key parts is constructed, and then according to the multi-objective optimization method and matching principle, Determine the active remanufacturing time domain of the engine.
