【摘要】：機械零件生產(chǎn)方案的制定是機械零件制造過程中的重要環(huán)節(jié),而且對機械零件的加工質(zhì)量以及加工效率有著非常顯著的影響。泵閥零件是火箭的關(guān)鍵零部件之一。近些年來,我國航空航天事業(yè)的快速發(fā)展,對泵閥零部件的加工質(zhì)量以及加工效率提出了愈加嚴(yán)格的要求。目前,該生產(chǎn)線的生產(chǎn)設(shè)備分配不合理,導(dǎo)致該生產(chǎn)線存在較嚴(yán)重的不平衡問題,生產(chǎn)能力無法滿足泵閥零件日益增長的產(chǎn)量需求。因此,急需對泵閥零件生產(chǎn)線進(jìn)行平衡優(yōu)化,充分發(fā)揮生產(chǎn)線的加工能力,從而提高泵閥零件生產(chǎn)線的加工質(zhì)量以及加工效率。本文基于裝配線平衡優(yōu)化理論對泵閥零件生產(chǎn)線平衡問題進(jìn)行研究和分析,對其工藝信息以及設(shè)備信息進(jìn)行轉(zhuǎn)換處理,建立平衡優(yōu)化數(shù)學(xué)模型。為了簡化平衡優(yōu)化數(shù)學(xué)模型的建立以及求解過程,基于VC++與Matlab聯(lián)合編程技術(shù)開發(fā)一套泵閥零件生產(chǎn)線平衡優(yōu)化分析軟件。該軟件的主程序框架在VC++MFC環(huán)境下進(jìn)行開發(fā),并通過OLE/COM技術(shù)實現(xiàn)泵閥零件工藝信息與生產(chǎn)線設(shè)備信息的導(dǎo)入與轉(zhuǎn)換處理,進(jìn)而建立泵閥零件生產(chǎn)線平衡優(yōu)化數(shù)學(xué)模型。針對其特點,對平衡優(yōu)化求解算法進(jìn)行研究,并基于蟻群算法的基本原理設(shè)計適合于泵閥零件生產(chǎn)線的平衡優(yōu)化求解算法。通過VC++與Matlab聯(lián)合編程技術(shù)實現(xiàn)基于該平衡優(yōu)化算法求解模塊的開發(fā)。針對求解模塊生成的結(jié)果數(shù)據(jù),開發(fā)結(jié)果后處理模塊,實現(xiàn)平衡優(yōu)化前后工序分析對比圖像生成、主要評價參數(shù)的計算與對比分析以及將平衡優(yōu)化方案保存為Excel文檔。通過Solidworks軟件建立泵閥零件生產(chǎn)線的3D模型庫,在Plant Simulation軟件中建立泵閥零件生產(chǎn)線平衡優(yōu)化前后工序的仿真模型。通過仿真結(jié)果對泵閥零件生產(chǎn)線平衡優(yōu)化分析軟件的有效性進(jìn)行驗證,并且對平衡優(yōu)化前后工序進(jìn)行對比與分析。在Lingo非線性求解軟件對泵閥零件生產(chǎn)線平衡優(yōu)化數(shù)學(xué)模型進(jìn)行求解,將求解結(jié)果與平衡優(yōu)化分析軟件的求解結(jié)果進(jìn)行對比,進(jìn)一步對平衡優(yōu)化分析軟件的性能進(jìn)行評價與分析。泵閥零件生產(chǎn)線平衡優(yōu)化分析軟件的開發(fā),能夠簡化泵閥零件生產(chǎn)線平衡優(yōu)化數(shù)學(xué)模型的建立與求解過程,進(jìn)而極大地縮短泵閥零件生產(chǎn)線平衡優(yōu)化方案的制定過程。泵閥零件生產(chǎn)線平衡優(yōu)化分析軟件的開發(fā)對提高泵閥零件生產(chǎn)線的生產(chǎn)效率以及加工質(zhì)量有著十分重要的作用。
[Abstract]:The formulation of production plan for mechanical parts is an important part in the manufacturing process of mechanical parts, and has a very significant impact on the machining quality and efficiency of mechanical parts. Pump valve part is one of the key parts of rocket. In recent years, with the rapid development of China's aerospace industry, the processing quality and processing efficiency of pump valve parts are becoming more and more stringent. At present, the production equipment distribution of the production line is unreasonable, which leads to the serious imbalance problem in the production line, and the production capacity can not meet the increasing demand for pump valve parts. Therefore, it is urgent to optimize the production line of pump valve parts, give full play to the processing ability of the production line, and improve the processing quality and efficiency of the production line of pump valve parts. Based on the balance optimization theory of assembly line, this paper studies and analyzes the balance problem of pump valve parts production line, transforms the process information and equipment information, and establishes the mathematical model of balance optimization. In order to simplify the establishment and solution process of the mathematical model of balance optimization, a software for balance optimization analysis of pump valve parts production line is developed based on VC and Matlab programming technology. The main program frame of this software is developed in VC MFC environment, and the process information of pump valve parts and equipment information of production line are introduced and transformed by OLE/COM technology, and then the mathematical model of balance optimization of pump valve parts production line is established. Based on the basic principle of ant colony algorithm, a balance optimization algorithm suitable for pump valve parts production line is designed. The development of the solution module based on the balanced optimization algorithm is realized by the joint programming technology of VC and Matlab. According to the result data generated by the solution module, the result post-processing module is developed to generate the image of the process analysis and contrast before and after the balance optimization, the calculation and contrast analysis of the main evaluation parameters and the preservation of the balance optimization scheme as Excel document. The 3D model library of pump valve parts production line is established by Solidworks software, and the simulation model of the process before and after balancing optimization of pump valve parts production line is established in Plant Simulation software. The simulation results verify the effectiveness of the software for the balance optimization analysis of pump valve parts production line, and compare and analyze the working procedures before and after the balance optimization. The mathematical model of equilibrium optimization of pump valve parts production line is solved by Lingo nonlinear solution software. The results are compared with the results of balance optimization analysis software, and the performance of the software is evaluated and analyzed. The development of software for balance optimization analysis of pump valve parts production line can simplify the process of establishing and solving the mathematical model of the balance optimization of pump valve parts production line, and thus greatly shorten the process of formulating the balance optimization scheme of pump valve parts production line. The development of balance optimization analysis software for pump valve parts production line plays an important role in improving the production efficiency and processing quality of pump valve parts production line.
