    摘要:

    优秀的飞机结构设计是民用飞机取得商业成功的必备条件,需要通过结构的可制造性设计来实现。面向可制造性设计可以大幅度降低民用飞机结构的成本、提高质量和可靠性,并缩短研发周期。越早启动面向可制造性设计收益就越大,在设计初始阶段就考虑可制造性,可以降低在制造阶段进行大量修改的时间和费用。飞机结构设计在满足功能和强度性能设计要求的情况下,还要考虑其他几个可制造性关键因素:简单的设计、材料的选择、合适的公差、灵活的备选制造方案以及技术数据的清晰和简洁。零件可制造性设计中材料和工艺的最佳组合可以通过一个程序性的方法对设计目标的三个方面进行权衡分析来获得。还提供了可制造性检查单,可以用来对零件和装配设计的可制造性进行评估。

    Abstract:

    Excellent aircraft structural design is a requirement for the commercial success of civil aircraft, and it needs to be achieved through structural design for producibility. Design for producibility can significantly reduce the cost, improve quality and reliability of civil aircraft structure, and shorten the development cycle. The earlier design for producibility is initiated, the greater the benefits. Considering producibility at the initial design stage can reduce the time and cost of extensive modifications during the manufacturing phase. The design of aircraft structures meets functional and strength performance design requirements while considering several other key factors of producibility: simplicity of design, choice of materials, appropriate tolerances, flexible manufacturing alternatives, and clarity and conciseness of technical data. The optimal combination of materials and processes in a part’s design for producibility can be obtained through a procedural approach to a trade-off analysis of the three aspects of the design goals. This paper also provides a producibility checklist, which can be used to evaluate the producibility of part and assembly designs.
