摘要

转子叶尖周向间隙不均匀会严重影响气动稳定性。因此,在装配过程中,各级转子叶尖的间隙分布应尽可能均匀。本文旨在通过优化转子-定子组件的装配工艺参数,最大限度地减少间隙分布的不均匀性。首先利用空间几何变换建立了间隙不均匀度的预测模型。然后,利用莫里斯法量化了各种因素对间隙不均匀性的影响。主要因素的归一化敏感度分别为:转子叶片尖端的跳动为 0.1242,机壳流道的跳动为 0.0998,后枢轴的偏心率为 0.7759。因此,后枢轴的偏心率是主要因素。此外,还根据敏感性分析结果制定了工艺优化策略。将后枢轴、转子叶尖和机壳流道作为优化对象,完成了转子-定子组件的工艺优化。试验结果表明,根据最优工艺参数优化转子-定子组件的装配状态后,整体间隙不均匀度与初始间隙不均匀度相比平均降低了约 85.06%。具体而言,与优化前的间隙不均匀度相比,优化后枢轴和转子叶片尖端后,间隙不均匀度分别降低了约 83.3% 和 11.65%。尽管对机壳流道进行了优化,但间隙不均匀度仍基本保持不变。

Optimizing compressor rotor–stator assembly process to minimize clearance non-uniformity

Optimizing compressor rotor–stator assembly process to minimize clearance non-uniformity

The circumferential nonuniform clearance of the rotor blade tip significantly impacts aerodynamic stability. Therefore, in the assembly process, the clearance distribution of rotor blade tips at all levels should be as uniform as possible. The aim of this paper is to minimize the non-uniformity of the clearance distribution by optimizing the assembly process parameters of the rotor–stator assembly. The prediction model for clearance non-uniformity was first established using spatial geometric transformation. Then, the influence of factors on clearance non-uniformity was quantified using the Morris method. The normalized sensitivities of the main factors were 0.1242 for the runouts of the rotor blade tips, 0.0998 for the runouts of the runners of the casing, and 0.7759 for the eccentricity of the rear pivot. Therefore, the eccentricity of the rear pivot was the main factor. Furthermore, a process optimization strategy was established based on the sensitivity analysis results. The process optimization of the rotor–stator assembly was completed by considering the rear pivot, rotor blade tips, and casing runners as optimization objects. The test results demonstrated that, by optimizing the assembly state of the rotor–stator assembly based on the optimal process parameters, the overall clearance non-uniformity was reduced by an average of about 85.06% compared to the initial clearance non-uniformity. Specifically, the optimization of the rear pivot and the rotor blade tips reduced the clearance non-uniformity by about 83.3% and 11.65%, respectively, compared to clearance non-uniformity before their respective optimizations. Despite efforts to optimize the runners of the casing, clearance non-uniformity remained largely unchanged.
