| Abstract: | An aeroelastic analysis system(AEAS) was been designed to perform aeroelastic analysis for three-dimensional turbomachinery rotor blade models.A time-marching method was applied in AEAS for transient displacement and dynamic stress responses of rotor blades,thus simulating aeroelastic phenomena in compressor rotors.Forced response and flutter analyses modules are two major aeroelastic modules in the AEAS code.In forced response analysis,periodic unsteady pressure field was applied to rotor blades at possibl... |
