航空发动机结构设计中可装配性案例分析

Instance Analysis of Aeroengine Structure Design of Assembly

为提高航空发动机的可装配性,保证产品质量,改善生产效率,从结构设计出发,针对现有分组、非均布、防错、考虑工装与工具等设计方法,结合典型案例进行装配工艺分析和总结,指出应当在发动机产品设计初期对形状、结构、连接等进行可装配性分析,总体上提高质量和一次性装配成功率。提出结构轻量化、连接自动化、虚拟预装配是今后发动机设计的重要方向。

In order to improve the design of assembly,quality and efficiency,based on the structure design,the design method of the existing grouping,non uniform distribution,error prevention,consideration of tooling and tools,combined with typical cases to analyze and sum up the design of assembly.It was pointed out that the design of assembly of the shape,structure and connection should be analyzed at the early stage of the design of the engine,and the quality and success rate of the one-time assembly should be improved in general.It was pointed out that lightweight structure,automatic connection and virtual preassembly were the important directions of engine design in the future.
