Abstract
With the development of the technology, the working conditions, which include high temperature, assembly and working state, have important influence on the dynamic performance of finger seal. Therefore, it is necessary to consider above factors together when the finger seal performance is carried out. But so far, the finger seal performance under considering several factors together have not been investigated. Based on this, the material parameters, which are needed in the dynamic performance analysis process of C/C composite finger seal, are obtained by the tribology test of C/C composite. Then the equivalent dynamic model of finger seal based on distributed masses is established under considering the rotor incline, temperature, assembly and impact together. And the dynamic performance of finger seal is analyzed by the model. The results are shown that the above working states have complex influence on the finger seal performance. Meanwhile, the leakage performance of finger seal is compared with those of labyrinth seal in the bearing chamber working environment, and the advantage of finger seal is represented. The dynamic performance analysis of finger seal under considering complex working states is carried out, and the theory research system of finger seal is further improved.
