| 论文摘要： |
In this study, the structural simplification of an aero engine’s cylindrical shell with sealing teeth and the design of dynamic similitude models are investigated. An energy method is employed to propose equivalent conditions that sealing teeth can be simplified as rectangular teeth. Appropriate equivalent conditions are selected by using numerical analysis method and the whole teeth’s equivalent model is designed. According to the Love theory, the transfer matrix of a thin-walled cylindrical shell with sealing teeth is derived from the governing equations. Further, under the condition of different materials, the dynamic scaling laws between the whole teeth’s equivalent model and the prototype are established based on the transfer matrix method. Finally, dynamic scaling laws are determined and validated by the numerical analysis. |
