Abstract

The transient dynamic stress analysis by cyclic symmetry method was presented in this paper. According to the characters of blade structure and applied exciting force, the cyclic symmetry boundary displacement equation was established. The calculation of cyclic symmetry boundary displacement in time could be changed to calculation of space. The cyclic symmetry dynamic analysis could be realized by applying cyclic symmetry displacement on the boundary of blade sector.
- cyclic symmetry,
- dynamic stress,
- air cooling turbine,
- blade
