摘要

装配是航空发动机制造的重要环节，装配质量的好坏直接影响发动机的稳定性和使用寿命。主轴惯量是影响航空发动机动力性能的重要因素。装配会影响飞机发动机的主轴惯量，进而影响发动机的动力性能。提出了一种基于加工误差传递的主轴惯量传递模型，研究了装配影响下多级转子主轴惯量的变化规律，提出了一种主轴惯量最小的优化装配方法。通过仿真和概率密度法分析了加工误差对主轴惯量的影响规律。所设计转子的装配结果验证了惯性传递和装配模型的有效性。结果表明，多级转子的主轴惯量受加工误差的影响，可通过改变装配方法来调整主轴惯量。本文为组合转子主轴惯量的传递与调整提供了一种新的思路。

A novel assembly method of aero-engine rotors with minimized spindle inertia

Assembly is an essential part of aero-engine manufacturing, and the assembly quality will affect the engine’s stability and service life. Spindle inertia is an essential factor affecting aero-engine dynamic performance. Assembly can affect the spindle inertia of the aircraft engine, which in turn affects the dynamic performance of the engine. This paper proposes a transfer model of spindle inertia based on machining error transmission, studying the variation law of spindle inertia of multi-stage rotors under the influence of assembly, providing an optimized assembly method with minimized spindle inertia. The influence law of machining errors on spindle inertia is analyzed through the simulation and probability density method. The assembly results of the designed rotors verify the effectiveness of the inertia transfer and assembly model. The results show that the spindle inertia of multi-stage rotors is affected by machining errors, and the spindle inertia can be adjusted by changing the assembly methods. This paper provides a new idea for the transmission and adjustment of spindle inertia of assembly rotors.

期刊介绍： Manufacturing industries throughout the world are changing very rapidly. New concepts and methods are being developed and exploited to enable efficient and effective manufacturing. Existing manufacturing processes are being improved to meet the requirements of lean and agile manufacturing. The aim of the Journal of Engineering Manufacture is to provide a focus for these developments in engineering manufacture by publishing original papers and review papers covering technological and scientific research, developments and management implementation in manufacturing. This journal is also peer reviewed. Contributions are welcomed in the broad areas of manufacturing processes, manufacturing technology and factory automation, digital manufacturing, design and manufacturing systems including management relevant to engineering manufacture. Of particular interest at the present time would be papers concerned with digital manufacturing, metrology enabled manufacturing, smart factory, additive manufacturing and composites as well as specialist manufacturing fields like nanotechnology, sustainable & clean manufacturing and bio-manufacturing. Articles may be Research Papers, Reviews, Technical Notes, or Short Communications.
