摘要

针对航空发动机扩压器整体叶盘内流道表面加工成本高和效率低的问题，提出采用磨粒流加工方法。通过建立有无上压盖及引流芯模的流道仿真模型，对比分析了两种模型下仿真流场的分布规律。在此基础上，对工件的夹具结构进行了改进并利用该夹具对扩压器整体叶盘内流道表面进行了磨粒流光整加工试验。结果表明：增加上压盖及引流芯模结构后，有效改善了整体叶盘大端和小端处的局部流场，解决了加工效果不一致和锐边被磨料冲蚀的问题，加工后流道表面粗糙度降低了0.6μm

表面质量得到了进一步提高。

Abstract

Abrasive flow machining (AFM) was proposed to finish the problems of high capital cost and low efficiency of surface polishing on the aero-engine blisk. By establishing the simulation model based on whether the blisk fixture tool contains the core mold and the gland

and compared the distribution law of the flow field in the simulation

redesigned the fixture structure to fit for the blisk. On this basis

the AFM processing experiment is carried out. The result shows that after adding the core mold and the gland structure

the AFM process can effectively improve the local flow field of the blisk

and solve the problem of the inconsistent processing effect and abrasive erosion on the sharp edge. The surface roughness of the flow channel is reduced by 0.6μm

and the surface quality has been further improved.
