| Abstract: | An advanced method has been presented for analysing the dynamic behaviour of annular cascade shrouded blades used in compressor and turbine rotors of engines. The method may be considered as the combination of chain loading technique and group algorithm. It is applicable to investigate the complete effect caused by blade shrouds. Its general analytical procedures and concrete equations are shown in the paper. The extension of dynamic analysis for structures which have both periodically cyclo-symmetric and annular cascade characteristics can be realized. Under the precondition that the computational accuracy is ensured, this method shows reliability, practicability and remarkably economic benefits. |
