An investigation of the interaction between Coriolis forces and mistuning on a cyclic symmetric structure is presented in this paper. The sensitivity of the eigenvalues and …
A successful design of rotating shaft-bladed disk (“blisk”) assemblies requires the facility to reliably predict the resonance speeds, which must be avoided during operation to avoid …
Dans une industrie aéronautique de plus en plus concernée par les enjeux environnementaux de notre époque, la maîtrise du comportement dynamique revêt un …
Over the last decade, Blade tip timing (BTT) has been replacing strain gauge (SG) systems for the measurement of the vibration of turbomachinery blades, reducing development times …
