大型客机起落架总体方案设计软件开发与利用 大型客机起落架总体方案设计软件开发与应用

采用数字化工程的方法将先前起落架总体方案设计人员的经验有效地进行存储。运用VisualC++和Oracle开发了大型客机起落架总体方案设计软件,以快速确定大型客机起落架的总体设计方案。收集整理国内外现有大型客机起落架的布局和结构形式,建立大型客机起落架布局和结构形式库、大型客机起落架缓冲系统范例库和大型客机起落架收放形式范例库。针对起落架总体设计参数的确定建立了伴随知识库并进行了工程算法研究。软件满足用户需要,达到提高飞机及起落架设计质量、缩短研制周期的目的。

Development and Application of the Initial Scheme Design System of Landing Gear for Large-scale Civil Airplanes

Conceptual scheme design software was developed by Visual C＋＋ and Oracle to determine the conceptual design scheme quickly. This method can well memorize the past experience of designers. First, the layout and structure format of the landing gear for large-scale civil airplanes in existence was collected. Furthermore, the example databases for the damping and retracting system of large-scale civil airplanes were given. Finally, the design parameters of the conceptual design scheme were studied with the knowledge database. As a result, the software is satisfied needs of customers and realized the purpose of improving the design quality of the airplane and landing gear, and shortening the developing time.
