| 英文摘要: |
| A appropriate optimization objective function was established and analysed using VBA program by analysing the
superposition mechanism of the concentricity,perpendicularity and unbalance of multistage disc rotor structure and the effect relation of
assembly parameters on unbalance for comprehensively optimizing the runout of rotor system and initial unbalance. Combined with practical
application experience,the runout errors were analyzed and corrected,and the optimal scheme was selected in the feasible range of
assembly phase relationship between different levels of disk. The results show that the dual objective optimization of the disk drum assembly
of a compressor can reduce the initial static unbalance by 86 percent and effectively improve the assembly quality and the assembly
efficiency of the rotor compared with the traditional stacking optimization scheme. The assembly process optimization method has a strong
engineering guidance significance for the aeroengine assembly optimization,decomposition inspection and connection surface quality
evaluation. |
