Model assessment of a composite mock-up bladed rotor based on its vibration response and radial expansion

摘要

Composite materials provide high strength and stiffness-to-weight ratios and adjustable directional material properties. As a result, a growing application of composite materials in weight-relevant and complex-loaded structures is noticeable, especially, for the production of high-speed rotors. However,. their material complexity, their parameter scatter and unpredictable impact events contribute to the prediction uncertainty of the operational capability.
