| Abstract: | By using the classical theory of rotor dynamics in this paper,we do a preliminary research on the problem for dynamic response and stability of the turborotor due to losing unexpectedly a few vanes in operation.In our analyses to this problem,some affecting factors,including the factors due to losing a few vanes,are comprehensively considered.From the re- sults obtained,we get some new physical phenomena through analyses,re- veal cetain characteristics on operational instability of the rotor concerning this kind of problem,and study out the condition for stable operation. |
