Refined FEM Analysis of 1000MW Generator Stator during Integral Transportation on Railway

Abstract:

A new designed 1000MW generator stator was planned to be transported by DQ₄₅ Schnabel car with end shield mode. In order to ensure the safety of transportation, three design schemes of end shield were proposed。In this paper, refined finite element models were established including frame of stator with different end shield, and nonlinear finite element analyses according to load condition of transportation on railway were performed subsequently. The numerical results indicated that load condition of structure could be improved significantly by using the third proposed end shield with tension bar, and the safety of transportation could be guaranteed. At last, the numerical results of the third scheme were compared with test data, and the reliability of finite element models was confirmed.
