摘要
The tip clearance distribution of multistage rotor and stator is an important index to measure the assembly quality of aero engines, and the traditional assembly methods arc difficult to accurately predict and control assembly clearance. In view of the above problems, a dynamic prediction and control method of assembly clearance of MRS driven by digital twin was proposed. On the basis of analyzing the assembly process, a digital twin model for assembly clearance control of multistage rotor and stator was established, which focused on time variation. Through the measured data driven service model, online prediction of assembly clearance and dynamic regulation of assembly process were realized. The twin data types and the fusion iterative process were sorted out. Four service models were built to realize data fusion iteration. The effectiveness of the proposed method was verified by the assembly process of a compressor. The evolution characteristics of the rotor stator assembly's digital twin model in the time dimension provided a basis for realizing the online prediction and dynamic regulation of multistage rotor stator assembly clearance. © 2023 CIMS.
