典型裝配工藝模塊化的應(yīng)用研究

Modularization of typical assembly processes

  • 摘要: 航天器類產(chǎn)品具有派生型號多、生產(chǎn)批量小等特點，因而存在工藝設(shè)計重復(fù)工作量大、效率低等問題。研究了基于典型工藝模塊化的參數(shù)化工藝設(shè)計方法。通過合理選擇裝配單元劃分特征，給出了有效的典型裝配單元劃分及鑒別方案，提出了基于典型工藝應(yīng)用規(guī)劃裝配流程的方法，并以“天宮一號”熱控多層組件制作為實例進(jìn)行了應(yīng)用過程分析。在“天宮一號”總裝工藝設(shè)計過程應(yīng)用的實際效果證明該方法切實可行，能夠提高工藝設(shè)計效率。

     

    Abstract: The process design of spacecraft products is usually characterized by high repeatability and low efficiency due to a large number of descendable models with each of a small batch production size. To deal with that problem, a parameterized approach for the process design is proposed in this paper based on the modularization of typical technologies. Through a proper selection of criteria in the division of assembly units, an effective scheme for the division and identification of typical assembly units can be formed, and the assembly process planning based on typical technologies is achieved. The application of the method is illustrated in an example of the fabrication of thermal control multi-layers for Tiangong-I target spacecraft. It is shown that this method is feasible, and can enhance efficiency of the process design.
