Popis: | A numerical analysis system has been developed for predicting forced vibration levels of compressor blades of a given blade row subjected to either wakes from an upstream blade row or potential flow disturbances from an upstream/downstream blade row. The system consists of an unsteady aerodynamic analysis and a structural analysis. The unsteady aerodynamic analysis based on an unsteady three-dimensional multi-blade row Reynolds-averaged Navier-Stokes analysis is performed to predict the unsteady aerodynamic load in a multi-blade row environment. The structural analysis using a finite element model is performed to get the mode shape and frequency of the blade. In this paper, the system is established on ITBL (IT-Based Laboratory) network, and applied to a rotor blade of High-Pressure Compressor. As a result, it is found that the pressure perturbation on a rotor blade is to be three-dimensional distribution and vary from blade to blade. 資料番号: AA0048469029 レポート番号: JAXA-SP-04-012 |
