【摘要】：随着我国基础设施建设规模和固定资产投资规模的扩大,对工程机械的需求也随之增加,产品技术和制造技术是关系到企业竞争成败的两大核心技术,各制造企业一方面通过技术改造来提升产能,另一方面投入大量资金和人力开展制造技术的研究,从而促进了制造技术的快速发展。单元化、线性化、数控化、自动化的制造系统已逐渐形成。装配线的实施应用快速提升了生产效率,然而,为了在竞争日趋激烈的国际市场上占得先机,对装配线的效率、生产成本等提出了更高的追求目标,这就要求应用先进的方法、手段来解决装配线的平衡问题。本文作者利用在某重型工程机械厂工作机会,以该厂的一条典型的底盘装配线为研究对象,利用Simio系统仿真软件建立装配线仿真模型,进行运行分析,找出装配线平衡方面存在的问题,然后结合装配线平衡的相关理论,对装配线进行深入研究,运用启发式平衡法重新分配装配线各工位作业,以达到提升平衡率的目的。对平衡改善后的装配线再利用仿真模型进行分析,并与改善前分析结果进行对比,取得实施改善的量化指标分析,从而为实施改善提供决策支持。本文所运用的研究方法和结论不仅对本文的具体研究对象具有直接的实用价值,同时,对于工程机械其它装配线而言,这种方法也同样适用。由于整体上工程机械行业的线性化装配技术发展滞后于汽车行业,利用最新的理论对工程机械行业装配线平衡进行研究目前在国内仍然很少,因此,本文的研究结论对工程机械行业线性化装配技术的发展以至推动整个制造技术的发展都具有积极的意义。
[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.
