| Abstract: | In the paper, the dynamic characteristics, such as critical speeds, vibration shapes and unbalance responses, of a simulated solid power turbine shaft for a new-type turbine shaft engine have been predicted using finite element method. Furthermore, the influences of balance collars on dynamic characteristics of the simulated shaft have also been analyzed. The predicted and experimental results show that the influence is small. They have nearly no change to vibration shape. So they can be used as ideal balance tools for slender high-speed flexible rotor. |
| Keywords: | turbine shaft engine simulated solid power turbine shaft dynamic characteristics balance collars balance tool |
