典型装配工艺模块化的应用研究

摘要

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.%航天器类产品具有派生型号多、生产批量小等特点,因而存在工艺设计重复工作量大、效率低等问题.研究了基于典型工艺模块化的参数化工艺设计方法.通过合理选择装配单元划分特征,给出了有效的典型装配单元划分及鉴别方案,提出了基于典型工艺应用规划装配流程的方法,并以“天宫一号”热控多层组件制作为实例进行了应用过程分析.在“天宫一号”总装工艺设计过程应用的实际效果证明该方法切实可行,能够提高工艺设计效率.
