【摘要】:隨著我國基礎(chǔ)設(shè)施建設(shè)規(guī)模和固定資產(chǎn)投資規(guī)模的擴大,對工程機械的需求也隨之增加,產(chǎn)品技術(shù)和制造技術(shù)是關(guān)系到企業(yè)競爭成敗的兩大核心技術(shù),各制造企業(yè)一方面通過技術(shù)改造來提升產(chǎn)能,另一方面投入大量資金和人力開展制造技術(shù)的研究,從而促進了制造技術(shù)的快速發(fā)展。單元化、線性化、數(shù)控化、自動化的制造系統(tǒng)已逐漸形成。裝配線的實施應(yīng)用快速提升了生產(chǎn)效率,然而,為了在競爭日趨激烈的國際市場上占得先機,對裝配線的效率、生產(chǎn)成本等提出了更高的追求目標(biāo),這就要求應(yīng)用先進的方法、手段來解決裝配線的平衡問題。 本文作者利用在某重型工程機械廠工作機會,以該廠的一條典型的底盤裝配線為研究對象,利用Simio系統(tǒng)仿真軟件建立裝配線仿真模型,進行運行分析,找出裝配線平衡方面存在的問題,然后結(jié)合裝配線平衡的相關(guān)理論,對裝配線進行深入研究,運用啟發(fā)式平衡法重新分配裝配線各工位作業(yè),以達到提升平衡率的目的。對平衡改善后的裝配線再利用仿真模型進行分析,并與改善前分析結(jié)果進行對比,取得實施改善的量化指標(biāo)分析,從而為實施改善提供決策支持。 本文所運用的研究方法和結(jié)論不僅對本文的具體研究對象具有直接的實用價值,同時,對于工程機械其它裝配線而言,這種方法也同樣適用。由于整體上工程機械行業(yè)的線性化裝配技術(shù)發(fā)展滯后于汽車行業(yè),利用最新的理論對工程機械行業(yè)裝配線平衡進行研究目前在國內(nèi)仍然很少,因此,本文的研究結(jié)論對工程機械行業(yè)線性化裝配技術(shù)的發(fā)展以至推動整個制造技術(shù)的發(fā)展都具有積極的意義。
[Abstract]:With the expansion of the scale of infrastructure construction and investment in fixed assets, the demand for construction machinery is also increasing. Product technology and manufacturing technology are the two core technologies related to the success or failure of enterprise competition. On the one hand, the manufacturing enterprises improve their production capacity through technological transformation, on the other hand, they invest a lot of capital and manpower to carry out the research of manufacturing technology, thus promoting the rapid development of manufacturing technology. The manufacturing system of unit, linearization, numerical control and automation has been gradually formed. The application of assembly line improves production efficiency rapidly. However, in order to gain the advantage in the increasingly competitive international market, the assembly line efficiency and production cost are pursued higher, which requires the application of advanced methods. Means to solve the assembly line balance problem. Taking a typical chassis assembly line of a heavy construction machinery plant as the research object, the author establishes the assembly line simulation model by using the Simio system simulation software, and analyzes the operation of the assembly line by using the opportunity of working in a certain heavy construction machinery factory, and taking a typical chassis assembly line of the plant as the research object. The problems in assembly line balance are found out, and then the assembly line is deeply studied in combination with the theory of assembly line balance, and the heuristic balance method is used to redistribute the work stations of assembly line in order to achieve the purpose of increasing the balance rate. The simulation model is used to analyze the assembly line after the balance is improved, and the results are compared with the results before the improvement, and the quantitative index analysis of the improvement is obtained, thus providing decision support for the implementation of the improvement. The research methods and conclusions used in this paper are not only of direct practical value to the specific research object of this paper, but also applicable to other assembly lines of construction machinery. Because the linearized assembly technology of construction machinery industry lags behind that of automobile industry on the whole, the research on assembly line balance of construction machinery industry by using the latest theory is still rare in our country. The conclusion of this paper is of positive significance to the development of linearized assembly technology in construction machinery industry and to the development of the whole manufacturing technology.
